Subject: Data Mining Myspace Bulletins

The same goes for forums; you can even read posts from private forums.
Unfortunately, you aren't able to tell which forum a post came from
just from the postID, and it is enormously difficult to guess what
postids might appear in which group, due to the high volume.
If any is interested in this (which I doubt), I've got a perl script
to slurp a range of them (which is way shorter than your C :P but
probably slower).
It can certainly be an interesting read though; people seem to have a
false sense of anonymity, judging from what they're willing to admit
on these forums.
