Reputation requirements compared
I've joined the recently-opened anime.se, and noticed that the rep amount needed to get certain privileges there is really small (it was just 2k for the "trusted user". Now, after 1 week in beta, the scores have shifted, increasing by 2 times - so now it's 4k for "trusted user" winch is still nothing compared to 20k here on SO. As I understand from searching the meta, the privileges themselves are based just on that rep requirement: so if, for example, a user has 2krep needed for Privilege A, and the next day the rep needed for that privelege is increased, the user loses it immediately.
Are these changes being done automatically, or manually by SE staff? And based on what criteria are they changed (i.e. each 7 days, each 100 users, etc)?
