Hi, I have noticed this concept prevalent in other forums where people create multiple id / account and upvote their own answers/questions.
Sometimes we see a lot of answers with lot up votes even when the question in concern doesn't get any vote.
or similar situations where you are lead to believe the person answering might be gaming the system by using 4-5 alternate id's.
is there any existing system i am unaware of that checks for things like this?
