I was a moderator for about 10 years on LU and developed a few systems to manage the trolls on that site. Drop threads and the fight club were both my original ideas - and dealing with the Union trolls in the international section was a big job I can tell you.
I was one of the original 7 members of LU (or Legends world of sport as it was known before LU), and as the only Knights fan, I started the Knights forum there. For the first 3 months it was basically me with 4 different user names writing replies to any knights fan who showed up, and if no one showed up, i'd write replies to myself and start new threads.
The point is, I did my time as a mod, and it was a pretty big job then. I just want to post in peace now.
