From what I know, it's what you get when you tweet 100 times in an hour, or 1000 tweets in one day. Basically twitter revokes your tweeting privileges for a few hours, though the times vary. Newer twitter members often get put in " twitter jail " by over-tweeting, in an attempt to get their tweet number higher. Hope I helped!
How do you get in twitter jail?
I've been on twitter for about 2 1/2 years, but I've never been in twitter jail. All of y friends, who are just recently joining twitter, have been in twitter jail multiple times. So my question is, How does one get in twitter jail?
