My mate, whilst we were trolling a site, and blatantly started picking on the Admin. Every little inconsistency and every fuck up. He was unfazed by any attempt to mock him and kept it up. Thing is he had done his homework. The Admin was self-conscious and inexperienced and was in fact struggling. He saw everything and saw it too struggling. His constant bombardment was causing other members to laugh at her and award him rep and other to leave.
Eventually the forum was stagnating and she did the unthinkable. She in trying to fix the forum fucked it and in getting it online admitted that she was not able to run it very well. She asked for suggestions.
Everyone was laughing at her and what have you but not him. He went into overdrive. "Do X now" "Do Y now" "Do Z if you want to save the forum".
Most of the advice was great advice. Some was designed to make her look stupid. With nothing to lose and not taking into account that part of the reason for the forum's demise was his negativity, she adopted almost everything he said. She put up with the results of the sillier suggestions because he actually came up with great suggestions too.
The forum saved and he was the saviour. THAT is a good troll Judy and funny as shit to see.
