This is so in vogue at the moment on our site.
In the last 2 weeks, we have had 2 members DEMAND their account be deleeted.
We complied, but under protest. They then went on to demand their posts and threads be deleted, in fact the latter of the 2 members threatened legal action.
He wasnt joking neither.
Unfortunately, we had deleted him a couple of days ago,.. so all his posts were set to guest.
This made the task of pruning his threads/posts nigh on impossible ... but we hacked the database, and changed his username.
In future our policy will be to NOT to delete a user but to change their username.
We have made changes to forum rules, and our account termination policy !
This made a good read:
