It was around 2010-12.
I already had an account I hadnt used much and couldnt log into because I couldnt remember password and it was on an email account I had no access to.
When I created the new account I wondered what was going on, it looked different, so I started trying out different features. Then the penny dropped. I just wasnt tech savvy enough and didnt have any real sense of vendetta, vengeance or destruction. I confined the shenanigans to two threads.
If it happened today I would move with speed and precision and not waste a moment. I would crop dust the whole joint and to hell with the consequences. I could edit and delete posts/threads, give warnings and infringement points and ban members.
meh, I probably wouldnt do any of it. Still not emotionally invested enough to care enough.
