This question already has an answer here:
Something strange has been happening on meta.SciFi recently...
But at least twice now, I've voted on the question and on several of the answers, only to have those votes apparently disappear.
The leading speculation is that it's due to the serial vote reversal script: since the question and most of the answers were posted by the same person, if you disagree with the idea of changing the name AND don't like many of the suggested new names, you're casting a lot of votes against the OP.
This raises a few questions:
Since this is a meta site, there's no reputation graph, so can you even tell if your votes are being reversed?
Since voting on meta doesn't cost points, should serial votes be reversed on a meta site?
If this is an artifact of serial vote reversal, how should a poll like this be conducted? (I'm less interested in this.)
