On my other question about nuking an account I guess I just realized that it must be possible to "self-nuke" in this way before randomizing your login. I dunno why that didn't occur to me above. I guess I withdrawl my question.
Its certainly possible to nuke an account, but Staff does not do it on request. I dont know why, but I can think of several reasons. E.g. someone that gained access to the account could request a nuke etc.
The way I do it for SAD (someone else linked it above) is that I start with the oldest posts and delete every post by hand. I also read each post to make sure (as beast as possible) that said post is not related to any scams and can safely be deleted. Everyone can - of course - just do this themselves, its just tedious and take a very long time. ~100 posts per hour is a reasonable speed.
If I were going to do this myself I'd just make a script. As you say, sounds very tedious to do this by hand. Then again you're reading each one. I'm surprised you don't charge more for this. Then again, I'm surprised that people feel the need to do this at all. LOL!
