No, unless you can get th staff to freeze an account. I don't think they've done that before for anyone, though. What you can do is nuke your account and start over. Many people have done that. Of what benefit wold it be to not advance anymore?

Not as far as I know.

1) If you don't like it to have an account with a particularly high level, because you would rather not be too exposed, the ideal solution is "Bagicide". You would rename your account, for instance, as "lobloblol-Bagicide" or whatever, and you won't use this account anymore. And then, you start a new account, and just forget the old one. 2) If you have a problem with your old account still getting a lot of points, you could minimize its chances to get points with following trick: - change your username to Anonymous and your avatar to the Bag. And erase all the information on your profile. You would probably get a lot less feedback afterwards. 3) you could also take some desperates measures with your old account, but they would not probably be much appreciated: - erase the contents of all your answers, and they would probably be flagged and rejected as nonsense. Normally, they should not get much points until they were all rejected. - don't flag anything from this account. - remove all your friends As a result, the only points you will get on this account will come from your questions. As there are quite a lot of people on AB trying to get points, your point amount should grow very slowly, and your ranking should lose at least 10 places per week. Because of this, you would get out of the top 1,000 Leaderboard after about a year.
