What is the best way for a search engine to discover and index South korean blogs?

This is what a few minutes of googling came up with:

"According to articles in the press, there are 5-6 million blogs.
[...] As far as I could tell, none of the blog systems used any of the
standard APIs, and some had RSS feeds. Blogs and hompys don't seem to
be pinging any pinger sites, which makes them nearly invisible to the
outside world. In addition, many sites block search engine bots from
crawling hompys and blogs. It appears that one of the biggest problems
is that there are several 800 pound gorilla type portals that remind
me of AOL during it's powerful years. They try to create walled
gardens of users."

That was one year ago. If this still is the case, is there any way to
get past these limitations? What would be needed to create and
maintain an index  of at least 75% of the South Korean blogs?
