Some interesting questions have been posed.

The poll can not be gamed in some of the ways implied; though lobbying and encouraging or discouraging other members can certainly be done (e.g. using signatures), it's legitimate.

The poll is entirely anonymous when it is set up to be anonymous, as this one is. Members, including Moderators, can not see who voted.

The parameters of the poll itself was established by the TalkBoard's request to the Moderators through their elected leader, iirc.

The wiki contains a POV summation and points pro and con. Any member with 90 days and 90 posts can edit a wikipost, so other pro or con points can be added. (Changes are documented always, so that's a check on any disruptive actions that potentially could be carried out.)

This poll will close on Jan 17, 15 at 8:14 am so perhaps discussing the actual topic is more of use to TalkBoard members and others than discussing how a poll works or if it can be gamed. I'm sure it could be, but the chances are nearly infinitesimally small.
