There is a creepy user who answered my question on Stack Overflow that I haven't accepted the answer with. He then keeps leaving a comment for like three consecutive days, asking for updates on his answer (which I interpret as basically asking me to accept his answer already). He also edits my old questions several times which I assume he is doing to get my attention. Well, he did.
My reputation count has been silent over the years with only occasional upvotes from old questions. Now ever since this creepy user started nagging me, my old questions suddenly gets a downvote once a day straight for a whole week now.
The thing is I've been here On Stack Overflow for 8+ years, and I've never encountered this. My silent reputation count suddenly getting downvotes along side with him nagging me makes me suspicious that it's probably his doing.
I understand that similar downvote attacks has been reported and systems are in place to detect this, but I think this creepy user could be deliberately doing it once a day at different times as to not trigger any alarms or he may even be using dummy accounts. Is there a way we can manually check on this?
