I'm not sure that any poll is totally safe from double votes. Someone can always make a second account, or refresh their IP. There's no way to tell if that's happening.

The polls on Wikia do stop double votes from each IP or Username, but they are subject to the same problems as any other poll.

That's one reason why staff want a discussion rather than just a poll for important community discussions. It doesn't stop fraud, but it makes it easier to spot, and staff can check for double votes with a checkuser (but only for very important discussions)

Btw, this isn't a blog post really, questions are best asked in the forums
