I recently got downvoted on four posts within a span of three minutes. I have read that such patterns are identified and reversed. Does my case qualify? If the same downvotes were exercised over a prolonged period of time rather than a few minutes, would the system be able to identify it? PS: I do not discount the possibility of genuine disapproval over the quality of my posts, but it seemed odd to be doing so successively on past questions most of which are resolved.
Generally, we do not make public the process of detecting "anomalous voting patterns."
Give it some time (24 hours). The script that detects anomalous voting patterns runs periodically. If it detects a problem, the votes will be reversed. If, after a day or so, the votes remain, flag one for moderator attention and explain the problem.
Moderators cannot determine who placed individual votes, but they have access to reports that might help help determine if there is, potentially, anything unusual.
