I recently improved and approved a suggested edit on a question submitted by a first-time user. The question was later closed as "Not a real question," which is all fine.
It appears that the user took offense with some part how the question was handled, and made three separate suggested edits in attempts to vandalize one of my own questions.
Two of the three were relatively minor edits, but they were all caught by the review system and rejected. While there was no actual harm done and the review system worked as expected, is there a way to stop this user from trying to make more of these edits on my or other users' posts?
