I'm curious. Can users with high 'reputation' unanswer a chosen answer? The reason I ask is because an answer I gave here was selected by the person that asked it as the best answer, yet about 15 minutes ago I lost the points for that answer, and it was unselected. Yet when I checked the person's profile, they have not been active for over 30 minutes.
I ask in light of the fact of decidedly dubious comments such as the one here, which asserts my answer is not an answer to the question (rather ridiculously)here
Random downvotes for perfectly fine responses.here
and the fact that someone has just transferred another question I answered to the beginners language section, resulting in me losing the points for answering it.
One or two of these events in isolation, I could chalk up to non events, but the volume and pace of them, I am starting to think someone is abusing their authority.
