If you mean Standard polls, looking like this: Example 1 2 Those polls count voters thru account or IP, so if they voted from their account, they'd have to use multiple accounts. If they're doing it while signed out, they'd have to change their IP to duplicate.

This is why Discussion polls are much better, since you can only vote in those if you have an account. (You also can't vote in these if you're blocked on the wiki in question) With these you can also see who all has voted, which you cannot see in wikistyle polls as above.
