I don't get it. Would someone please explain? Why do they do it? What do they get for doing it? Why always the text at the end taken from somewhere or completely scrambled? If I open the message do I open myself to more? (I never click on their URL if they provide one) How are they getting my email address? I need a basics course in the whys and wherefores of SPAMMERS examples below: # 1: Hi, CzIALIS AzMBIEN VzIAGRA VzALIUM http://antirsteek.com Bilbo. You have nice manners for a thief and a liar, said the dragon. You seem familiar with my name, but I dont seem to remember smelling you #2.

Spammers are using various creative methods to subvert spam-blockers. This sometimes results in some mighty peculiar emails. I've gathered material on some of the methods that are used. "The addition of seemingly nonsensical words is aimed at confusing the antispam filters that incorporate Bayesian analysis techniques, such as SpamBayes and SpamAssassin. These filters examine incoming e-mail messages and calculate the probability of it being spam based on each message's contents... By throwing a hundred or so random words rarely used in sales spiels into each e-mail missive, spammers hope to thwart Bayesian filters by making the spam appear to be personal correspondence. Incorporating words that might be used in legitimate e-mails is also intended to poison the checklist the filter uses, forcing it to mark, for example, e-mails with somewhat common words like Amazon and fish as spam indicators. The strange strings of words, which usually appear at the bottom of spam and sometimes in the subject line, are automatically added by spammers' mass-mailer software, according to Steve Linford of Spamhaus, an antispam advocacy organization. 'This random noise is technically known as a hash buster,' Linford explained." Wired News: Random Acts of Spamness http://www.wired.com/news/infostructure/0,1377,61886,00.html "Spammers try to circumvent the email filters by intentionally misspelling common spam filter trigger words. For example, 'viagra' might become 'vaigra', or other symbols may be inserted into the word as in "v/i/a/g./r/a". ISPs have begun to use the misspellings themselves as a filtering test." Wikipedia: Spam (electronic) http://en.wikipedia.org/wiki/Spam_(electronic) "Bayesian spam filters... look at the content of a message and 'weigh' the presence of spam-related words (e.g., 'viagra', 'remove', etc.) against the message as a whole. If you can contrive to put enough 'neutral' text in your spam message, you might be able to drop it below the statistical threshhold of such filters. And so, spammers will often introduce lots of unelated words or phrases, sometimes inside the HTML markup (but often outside it, after the final </HTML> tag. Sometimes they mask the words by making them the same color as the page background, or putting them in a comment. Often, the words are quotations from some unnamed literary work, but they may just as often be randomly generated strings of words. In the most recent spams I?m getting, the ratio of bogus text to real text has increased markedly, and the spammers are also no longer always bothering to make it invisible. When combined with the 'creative misspelling' trick, this results in sales pitches that are almost complete gibberish." Rick's Spam Digest: Popular spammer tricks http://rickconner.net/spamweb/tricks.html "A Web beacon is an object that is embedded in a Web page or e-mail and is usually invisible to the user but allows checking that a user has viewed the page or e-mail. Alternative names are Web bug, tracking bug, pixel tag, and clear gif... Typically, a Web beacon is a small (usually 1×1 pixels) transparent GIF image (or an image of the same color of the background) that is embedded in an HTML page, usually a page on the Web or the content of an e-mail. Whenever the user opens the page with a graphical browser or e-mail reader, the image is downloaded. This download requires the browser to request the image from the server storing it, allowing the server to take notice of the download. As a result, the organization running the server is informed of when the HTML page has been viewed... Web beacons are used by e-mail marketers, including spammers, to verify that e-mail addresses are valid and that the content of e-mails is actually viewed by users. When the user reads the e-mail, the e-mail client requests the image, letting the sender know that the e-mail address is valid and that e-mail was viewed. The e-mail need not contain an advertisement or anything else related to the commercial activity of the spammer. This makes detection of such e-mails harder for mail filters and users. Tracking via web beacons can be prevented by using mail clients that do not download images whose URLs are embedded in HTML e-mails."

Strings of random words or phrases are often "hash busters." This may be helpful: http://www.answers.google.com/answers/threadview?id=422726 |

That's helpful, thanks Pink . . . I imagine inserted 'z' into the names of drugs they're selling is another way to avert the spam filters are they simply playing a numbers game? a certain percentage of all the millions that go out will actually take the bait . . . ? all the spam I'm getting these days all have CC's to a number of other addresses that all have our ISP's address after the 'at' sign . How are they getting into the ISP's system? Our ISP has never been able to provide a real explanation for this, but the spams are getting more and more frequent. I resent having to take the time to put each one on my filter's black list! and does it endanger me in any way if I open the message? ps. I went to spamcops.com but they don't seem to have instructions for Mac Mail which is what I'm using these days. They don't even have Entourage, it looks like . . . or is that part of Outlook Express? puzzled and confoosed *** |

They are playing a numbers game. Amazing as it may seem, there are people who respond to spam. The cost of massive numbers of emails is so small that this method of peddling one's wares doesn't require a huge response in order to make a boatload o' bucks. In addition to the money from sales of the product, the spam-sucker customer's name and contact info may become sources of additional revenue for the spammer. Buy from a spam email, and -- as if by magic -- the number of spam emails you receive will multiply almost immediately! Wow! Instant popularity! |

Unbelievably, some people are stupid enough to take the bait. Since sending email is basically free, even 1 response out of 10,000 can be very profitable. I've noticed the same thing about all the email addresses being in the same ISP. They don't have to get into the ISP - I guess that they either send it to every email address that they have from that ISP, or maybe they use a dictionary program to generate possible email addresses. Yes, opening the email can be bad. If you have HTML enabled, your mail program may open any embedded images, which lets the sender know that you opened that email. |

Pink, I think you should post the answer, since you pretty much answered the quest . . . but here's a bonus question: (ha!) one spammer actually provided an 800 number to call to sign on to their get rich quick product. I'm looking for ideas on creative ways to call them and give them what for . . . any suggestions? (I must be trying to avoid something in my life if I'm willing to spend time doing this . . . yes, it's true) *** |

If you can access your e-mail on-line I highly recommend you first scan it there, delete everything you don?t recognize. Anything that you are not certain off send to a filter folder like the ?Junk? one Hotmail has or the ?Bulk? folder Yahoo gives you, all images are always blocked by default. If after you?ve seen the contents of the e-mail and it comes from somebody you know but it is empty with an attachment chances are that it is a virus/worm etc. unless Susie Q. tell?s you ?hey Time, I?m attaching XYZ here for you? again delete it. In that manner you will never get anything, and since you are being very liberal with the delete button and you will let your friends & family know about it, if they want to reach you they will put it on the subject line. Delete ?em all. |

timespacette, Regarding "creative ways" to contact the spammers' 800 number, please consider that anything you do is likely to have much more impact on the folks who answer the phones than it is on the spam tycoons at the top. I feel sorry for the people who do this kind of work, and I wouldn't want to make things any worse for them. I have several friends who have worked on inbound toll-free sales lines, and it can be a high-stress, low-income job. I'd be glad to prepare an answer for you with links about hash-busters and such things, if that would be fully satisfactory. |
