The common misconception is that 500 requests a day is the limit. This is no longer true. Ever since the blackout the crackdown became much more intense. A lot of my aquiantances have been complaining about it lately. A few days ago I did 200 limit run and got flagged down by myspace. I'm sitting around waiting to see what they will do, I hope they don't erase my account. It's kind of ridiculous. I'm freaked out now and don't even know if I should add more than 50 a day.
When they do crack down which is inevitable considering the abuse, I hope they take into account whether the friends of a particular account were at the request of each friend or that account making an outragous number of friend requests. I have over 16,000 friends. All at their request.
