There is a person on twitter who has made it her mission to report people she "thinks" are spammers or are violating the TOS. I post no more than 2 marketing messages a day, the rest are one liners, jokes, etc. Clean as a whistle. However, she has appointed herself as the Twitter spamcop and reported numerous people myself included for ridiculous crap. I've blocked her and some others have also. If enough people block her, they will suspend her acct. via the TOS. The username is "thatkwazygirl" check her out, you'll see what I mean.....what a bitch!
