That's a pretty good question.

I am able to vote on polls even when I am logged out on wikis (test source: undertale wiki main page), so an account is not required to vote in polls. Therefore, I think people who get blocked can also vote on polls as well, since the poll doesn't consider the account of a user (their browser/ip address instead). This is why Polls are unpopular on the wiki network, and a better alternative is to create a Discussions post asking people to say "support" or "oppose" (or what you want as options) as a comment.

In the future, I recommend asking questions on Special:Forum instead. Blogs aren't normally looked at for questions, so you could seek out more answers to your question to be certain (mine could be semi-right, for example).

Cheers!
