From my email (March 29, 2014):
Do you have tips on how to "fix" the problem with Twitter's Follow Limit Rule? I am following 4505 tweeps at the moment, but I "only" have 4098 followers, so I can't follow new tweeps right now. I have been testing different services for getting rid of inactive users, fake users, robots, etc. I recently tested www.unfollowers.com. Have you heard about other services? And why is Twitter sticking to this rule?
