I really don't know what gets into some folk at times.
Have different opinions and get into a debate ... I do it all the time.
... but remain civil ( well ... 'ish ).
I must admit that I actually find them more entertaining than an actual nuisance ( anyone else feel like that ? ).
I think they should be allowed to post in a special Troll section. Call it " Under the Bridge " or something like that.
When members are a bit bored with the airgun threads, or if the missus or kids have done your head in that day, you can go in " Under the Bridge " and bait the Trolls.
Maybe after a couple of weeks they may be cured and can be allowed on the rest of the board. It could be like therapy.
