All of those are hacks.

TBH, the best way to do it would be to have votes sent to an email address set up for this purpose, with their username. To add a bit of verification, they could also add a code word of their choice, and then post that code word with their wiki account on a given blog. Then just check that the message contains the code word and that message was sent before the posted the word on the wiki.

Sure, it's a hack - but would be more transparent than AbuseFilter.
