From Interference Policies and Rules:
"Trolling: Intentionally disrupting a forum by posting obviously inaccurate or inflammatory information and/or hoping to get a rise out of people. The perpetrators are known as 'trolls'. This also may also apply to our members who decide to 'troll' other forums. Should this lead to problems on OUR forum because of it, you may be banned.
*An 'Internet troll' or 'Forum Troll' or 'Message Board Troll' is a person who posts outrageous or sarcastic messages to bait people to answer."

"In general, using alters to violate Forum Rules/FAQs, voting multiple times in polls, as well as other common sense 'no-nos' will result in the banning of the alters and possibly the banning of the original username. Remember that alters are a privilege."
Still sounds like it's arguably in violation.
Regardless, we should definitely all commit to Headache's suggestion of blocking.
