Like I said at the bottom. Have the webmasters cross-check the signups vs. what accounts have been used in the past 30 days. That would weed out someone who just creates 10,000 accounts and waits for the poll. Unless you're going to sign on to the forums with all 10,000 accounts?
Of course, they should also increase the diligence of the webmasters anyway, I would hope they would notice 10,000 registrations from 'joeblow.com' or whatever in a 24 hour time period... Or total for that matter.
