It's just not worth it IMO, not worth risking and loosing friends over or for the few dollars, those that do sell bulletins are spamming their friends and as a result their friends will ignore them or realise that they're spam accounts - or their accounts are full of spammy friends aswell.
Maybe myspace update their capcha code too often and people just don't want to waste money to buy friend adder bot?
You don't really need a bot, just a hot picture for profile and then be active for a few days, post comments on popular blogs, chat in forums, comment on popular videos, upload a video and get lots of views, use chat rooms etc. Just look real and desperate males will hunt you down soon enough - they want active females who will chat to them - so leading them on is kind of gay, cruel, decieving, funny and it works.
