It wont take you long to work out who the main culprits are when it comes to trolling, best is to just ignore them and not rise to the bait.
There are also a few real tools who use this site, again they may not seem to troll 100% of the time, but best ignore them or they will hijack your thread and start agruing amounst themselves over nothing. This usually means an innocent thread will be closed by the mods.
Overall dont take anything seriously on here, but at the same time enjoy the banter, there have been some classic threads over the years that have been enjoable to watch build up.
Happy New Year
