it should be possible keeping posts yet deleting accounts. only thing, the username on the post seems anonymous or something like that. I think that should be a right for users to be able to do that.
people generally want to go away with their content.
Well, it is good but sometimes it shouldn't be. Scammers tend to clear the account most probably to make another scam and the the threads and/or posts will be deleted which makes it hard to know which was his previous account was. If we make a rule such as "posts and/or threads of scammers won't be deleted", it may become another problem. There are scammers who want to start fresh too. Unfortunately, current system won't allow these things unless you come with a new account, new address and new IP. Never and ever send from/to old address which you used to scam. This will help you to start fresh.
i think the right management for this case,
it is to delete user account plus his contents.
If a mod decide to bann an account it means who is posts are useless.
IMHO no. An account is banned if
majority of the posts are spam. There maybe a small amount of posts which are helpful.
And for this reason, i think if a user account is gone, contents need to gone with him.
Shouldn't be IMHO. One of the reason is in the reply to emrebey's post.
otherwise it would not be happy to ban a user.
All low value/spam posts will be deleted, anyway. I don't think there is a need to delete other posts.
