I happened to notice this odd behaviour twice recently and I'm wondering why this might be happening. For me this is kind of strange as the questions were legit ones before the edit. Also with valid answers that showed much effort put into them.
Now I can see a closing votes on those as they appear spam but before the edit they would probably never got those votes.
Can something be done to prevent this behaviour? Can Mods revert to the original question & prevent the author the edit again? Should this be done?
