Maybe once a month, I just get a random boost of maybe 15 upvotes in a very short timeframe (about an hour). Looks like somebody just ran down my question/answers and threw upvotes on everything. (Questions seem unrelated on category/score, I seem to be the only link between them all)
Really wonder where are these coming from? Any explanation? Bots trying to seem human by giving upvotes to a random human user or something like it?
Also is it something Arqade/SE should look to eliminate?
