I remember them doing so. A time limit would be good. I think 1000 character slots is way too generous too.
Sadly, they don't have a way to prevent multi-box accounts, though that really should be a part of the code-of-conduct.
The solution that the live game had was they did a name purge about 2 times on accounts that didn't log in for x amount of time. That wouldn't seem to apply at this time here.
Personally, I'm in favor of a Champions-type naming convention. Arcanaville was opposed to that due to privacy issues.
