On being banned by Twitter

Susan Johnson was one of the people banned by mistake from Twitter over the weekend. She ponders what it means:

... emailed support begging them to restore my account and promising to be a better citizen of the Twittersphere (though in truth, I think I'm already a pretty good citizen). This morning, with just as much warning (meaning zilch), my account was mysteriously back to normal. There were no signs of a hacker, and Twitter didn't even bother to send me an automated email (Dear Twitter: I know you know how to send automated emails because I get several per day!).

I'm happy to have my account restored and I realize that Twitter is a free service (for now, at least), but I'm also a little miffed that they can suspend someone with zero warning and without even an automated courtesy email explaining why. ...

Another banned Twitterer, Tom O'Keefe, reports, in the comments here that without Twitter, he was forced to use a phone to call a friend to meet for some ice cream at JP Licks.
