The wiki definition of trolling is:
In Internet slang, 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.
People disrupting posts or baiting others will not be tolerated on the CoD forum.
I recommend people read the rules here, with particular note to number 3:

If you break these simple rules, action will be taken.
