Some time ago (in January), I noticed a (-200) reputation change due to voting reversal. Someone just upvoted 20 of my posts within 5 minutes:
I thought this was an isolated event, perhaps a user who was after a voting badge. But, looking at my recent reputation history, I see that the voting didn't stop, the pattern just became more careful:
I see it always happens around the same time, though not every day. The number of upvotes varies, sometimes it's just 3 or 4, sometimes around 10 as in the screenshots above.
Could the mods please take a look at this?
Note to my mysterious benefactor: I'm sorry if I come across as ungrateful, especially if this post gets you punished for all the good you've been selflessly doing to me. Truth be told, I don't even care that much about the reputation I have, as long as it's above 2000. Please stop this and let everyone have just the votes they deserve, OK?
