Old accounts purged?

Are old accounts ever purged? I see a lot of users who haven't moved in a year or two or more. Even worse, many of them have 0 games played and very few moves--the user started a game or two, made a move or two, then left the site, never to return. I think I've even seen some with no moves at all! Do the mods ever clean out this clutter? Thanks.

No, and No.

No worries.
