Any users that insist I remove their account, I just change their username to something before removing their account and do not remove their threads/posts, so when their posts change to 'guest' their original username is no longer there.

If it's just a fairly non active account with little or no posts, then whatever. But I've had several users with 1000's of posts insist I remove their account for whatever reasons.

Also, I no longer allow super-mods/admins to hard delete threads since one decided to remove everything she ever posted and take off one day.

Right, therefore US laws apply. That's why Germany can stick it. :D

I saw that option when I wanted to suspend my account from a fairly busy site.
It also gave me an option "Delete all posts as well?" and I clicked OK, and disappeared from that site with no trace.

Admins there do not care what the contents is (only that it is civil and no usually forbidden things as on most sites), all they see is number of visits to show when selling ads space.

They (I think rightfully) deem all posts worthless drivel, even thought of deleting circularly everything older than 30 days.
