I was just answering a question and saw the following happen (not the first time):
The user who left 2 comments got them both upvoted immediately. My answer and comment which i had posted just before him were almost identical and didn't get any upvotes.
Is there a way to see for SO if there are users who are using 2 or more accounts to upvote themselves all the time?
I mean if some users post an answer or comment and it's the same account upvoting those it should be pretty easy to filter out right?
