Hi! It's nice to see you back in this end of the 'net!
So...spammers. Hate 'em. Annoying little nusiances who,
unfortunately, aren't doing anything illegal as long as they comply
with the spam laws of the state to which they're sending the spam.
Most states with spam laws require that a spammer:
-- not forge routing information (headers)
-- provide an "opt out" or unsusbscribe method, including a valid
-- not transmit his messages via a third party's server without
-- depending on the state, include the tag (ADV:) or (ADV: ADULT)
States with anti-spam laws enacted also make it illegal to "assist
with transmission" of unsolicited commercial e-mail. "Assisting"
appears to include:
-- operating an open relay (meaning anyone can use your mail server,
-- allowing a spammer to continue transmission through your network,
either by not disabling his account or not closing an open relay.
Although most statutes provide for the ability of spam receipients to
sue the spammer (or an unscrupulous provider who refuses to take
action against one of his users), the receipient must prove damages to
prevail, rendering such anti-spam legislation essentially toothless.
You can have a look at spam laws by state here:
Spam Laws - Summary
Spam Laws - by state
If you receive notice that one of your users is spamming, how you
should proceed depends on your Terms of Service (aka Acceptable Use
Policy). If your TOS states that you will disable accounts first,
pending investigation, then do so. If you don't have a "no spam"
clause, you'll want to update your TOS to include one. Many providers
use this method, because people *do* occasionally end up falsely
accused of spamming. Notify your user that you've received a spam
complaint and will be disabling his account until you've investigated,
and that the account will be deleted if he a) doesn't respond
satisfactorily or b) is found to be spamming.
As it happens, I was recently accused of spamming after someone
decided to include multiple links from a consumer awareness site I
maintain, and spam the daylights out of every address he could find.
My provider's policy is such that even if a link to your site is
included in a piece of spam, your account will be disabled until you
can prove to their satisfaction that you had nothing to do with it.
You might want to pattern your own notification after it:

We have received reports from our upstream network regarding links to
your site contained in spam email. We have viewed the reported spam
email and it does appear to have links going to your site.
Could you please let me know about your knowledge of the source of the
spam. At this point we have suspended the site. We must do this when
we receive an abuse report or our upstream network connection can be
cut to the entire server.

I wasn't the spammer, and was able to prove it with my logs and a copy
of the complaint sent to the person who sent the e-mail demanding that
he remove all references to the site, as well as a complaint to his
If your user doesn't respond or if you find upon review that he has
been spamming, you need only delete his account, in accordance with
You are not, according to any spam law listed above, legally obligated
to do more than that. If someone wants the spammer to be sued, it's
his responsibility to sue the guy, not yours.
To make sure you're extra secure, do ensure that you're not running
any open relays, and consider tightening up your TOS (if you haven't
already). Make certain all of your users receive a copy of it when
they sign up, and keep it posted on your website as well.
I hope this sets your mind at ease! Please do ask for clarification
if you need further assistance. I'll be happy to help!
