This question has lain dormant for months. It wasn't bumped, nothing happened. Suddenly, I get three downvotes (and one up vote) within a 24 hour period. How can I be sure somebody isn't meat puppeting or sock puppeting? Can an admin review the votes and assure me that it was a legitimate coincidence? Is it even possible?

The answer is cold fusion related, and it was at a (suprising) +1 before the current episode. It is possible that you have community vigilante patrols looking for oddball answers, I don't know. But it is not plausible that three votes come on a long dormant answer in a few hours. That has never happened before, and is unlikely considering the reduced traffic on the site.
