Twitter 2.0 suspended a bunch of my legitimate accounts without any explanation. Also, my personal account, opened in February 2007, is also in some kind of read-only mode - I cannot change my name. Actually, I don't want to change my name, just to remove some emoji suffix. The error I'm getting is "Account update failed: Denied." Twitter 1.0 sucked, but 2.0 sucks even more!
