I didn't think you could even see who had liked or disliked a post anyway so how would you know?
Exactly, making unfounded accusations is just guessing and in this case was wrong. All it's going to do is generate bad feeling.I removed the posts concerned and made it into a generic 'don't do this' announcement as a reminder instead of sending a PM ... because last time I sent a PM the same person got offended and upset that it wasn't done as a general announcement to all ...
I guess you just can't win - some people just don't want to be happy.
Also, as a reminder, you can change your vote on a post if you made a mistake by clicking the other one instead.
The voting for moderation would work fine in this case, there really wasn't any issue. But things work less well if people are allowed to harass other people over imagined votes.
