There's been some discussion on the site over whether some people would use multiple accounts to thumb down a particular person's bet into oblivion for spite. While we certainly wouldn't condone such a nefarious practice, the problem is not so pervasive as recent discussions would have anyone believe.
To be clear, thumbing down a bet is every user's right, for whatever reason they see fit. Every person gets one vote, and they can use that vote any way they like. The only thing that really matters for thumbs up and down is whether the ratings add up in the end to a positive or negative -- good bets should get a positive rating, and bad bets get a negative rating. There's enough users on the site where even if a question temporarily receives a bad rating, other users will come along and get things back on track. From what we've seen, the system is working pretty well.
Now, creating multiple accounts to weight your vote is definitely not allowed on dotblu. So if you think that's going on, please report it to the admin at firstname.lastname@example.org and we'll look into it. But if we don't take any action, it probably means that we didn't see a problem. A lot of the complaints we've received lately were just assumptions, and we can't stress enough that you shouldn't necessarily trust an assumption. Let us verify it.
And please don't post accusations on the site that can't be verified, it just goes to stir up arguments, animosity, and creates more problems than it solves. If you have any complaints or suspicions, don't hesitate to contact us, we will take a look.
