According to http://en.wikipedia.org/wiki/Internet_troll:

"An Internet troll, or simply troll in Internet slang, is someone who posts controversial and usually irrelevant or off-topic messages in an online community, such as an online discussion forum, with the intention of baiting other users into an emotional response or to generally disrupt normal on-topic discussion."

General Response

Trolls can simply be ignored. Their greatest weapon is the use of inflammatory comments and remarks with the deliberate intention of inciting irritation and garnering heated responses from legitimate users. Resist responding to such messages.

One in Particular

There has been a particular troll present on the mailing list for some time now. Many users, including myself (Chris Lewis) believe that he has been posting under many different aliases. We assume this for obvious consistencies: tone, voice, content, and conclusions (generally references to the Wicket framework are included). In dealing with this particular troll, I have opted to start reporting him to the abuse departments of the networks from which he sends messages. If you feel compelled, I urge you to do the same in addition to ignoring him completely.
