I've just experienced my first revenge downvoting spree, undoubtedly in response to my comment on this question. I posted a comment which a user took offense to; a little later I have 1 new downvote on each of my questions. Not really surprising; the user has a history of abuse on SO.
I'm not worried about the downvotes themselves. I know the abuse-detection system will probably detect this and remove the downvotes, so I'm not very concerned about my rep. What I'm wondering is whether, given the user's pattern of bad behavior on SO, it's appropriate to report this in order to draw further attention to his actions.
- Do moderators always look into abusive-voting patterns automatically detected on SO?
- If I see suspicious activity that will probably be caught automatically, should I report it anyway?
- I know suspicion of sock-puppet self-upvoting leads to account merges, bans, and other consequences. Does revenge downvoting have similar repercussions when detected automatically?
- Finally, given that this guy has already been recognized as a problem by other users, should I spend more/less/the same amount of effort in drawing attention to him?
