It started on a particular Q, Wherein, I had a rub-in with a particular user over one of my answer. Immediately,within seconds, there was surge of downvotes(>10) on me,I queried this user in the comments about it & this user agreed it was him who downvoted and bragged it was within his rights to do so & that SO policy allows him, We had an heated argument over it, following which the user deleted his comment.
On that ocassion the Fraud detection algorithm detected and reversed the downvotes.
After the incident I have been on the receiving end of regular serial revenge downvoting but that user seems to have wisened up & learned to game the system, The downvotes happen but just enough to not trigger the Fraud detection.
Few noticable ones:
Oct 6: 3 Downvotes
Oct 5: 3 Downvotes
Sep 21: 5 Downvotes
Sep 22: 2 Downvotes
All anonymous, with no real reasoning.
Every time I see the downvotes happening, I can see this user is active and on almost all occassions I could match his vote casting pattern with the downvoting against me.
Even yesterday,He posted a wrong answer & I just pointed the incorrectness(without even downvoting) & the response is a quick 3 downvotes(which you upvoted) where in there was no reason for any.
I have flagged for moderator attention & the mod said there is nothing they can do to write to [email protected]. I haven't written them there yet, but this whole situation is rather disturbing. So that's the story, without the who part in it, but i sure know who the Ass hole is.
Note that I know that these are only mosquito bites to Als' rep, but I still believe that such users are severely damaging this site's usefulness, not to mention its reputation. (This affects answers to questions where one down-vote makes a considerable change to which answer is up-voted most and thus seen as the right one by others searching for solutions to the same problem.)
This user knows exactly what he is doing. He is trying hard to fly under the vote fraud script's radar and thus keeps it always along the edge of "but I consider those wrong!". (However, the half a dozen questions and answers I have checked which were last affected by this are all factually right and at the very least deserve no down-vote; some deserve up-votes instead.) He takes out is incertitude on others, repeatedly, and Als might not even be his only victim.
IMO such users should be banned for a while, and for all eternity if the repeat the offense after the ban is lifted.
