Internet Trolls

I watched a BBC programme on "Cyber Bullying" last week and learnt about "Internet Trolls". The following is Wikipedia's definition:


A troll is someone who posts inflammatory, extraneous, or off-topic messages in an online community, such as an online discussion forum, chat room, or blog, with the primary intent of provoking readers into an emotional response or of otherwise disrupting normal on-topic discussion. The noun troll may refer to the provocative message itself, as in: "That was an excellent troll you posted". 


A troll!
"In anticipation of trolling becoming a problem on www.ms-res.orgwww.multiple-sclerosis-research.org we need some advice about how to deal with this problem. Any thoughts?"
