Twitter: Please get rid of the abusive Twitter "brandjacker" troll

I'm being harassed on Twitter by this abusive person: twitter.com/markmayhew.

I reported the abuser to Twitter. They've "taken out of circulation" two of the impostor accounts. But the troll sets up new ones just as soon as the others are taken down.

Surely blocking the IP address is the only solution? Twitter tells me that's not their normal policy but are looking into it to see how much the TOS have been violated.

This person is in serous violation of #4: You must not abuse, harass, threaten, impersonate or intimidate other Twitter users.

Numerous other Twitter members have reported this same person, yet he's still at large harassing, slandering and abusing me and many of my friends by pushing out offensive tweets.

Current active fake/brandjacked accounts include:

@marismiith (2 i's in smith)
@whyfacebook (name of my blog)
@twittersqueeze (mimicking my friend @Rick_Butts)

Current active accounts (that I know of):

@markmayhew
@twittertutor (yes, he "markets" himself as a twitter specialist)
@facebookeconomy

This abusive person has been *banned* from Facebook and Wikipedia. It's time he was BANNED from Twitter.

http://twitter.com/marismith - the ONLY account I use. All others are fakes by this troll.
