I wouldn't take any poll too seriously as it's very easy for anyone to manipulate them. DS is the only one that is very difficult for anyone to manipulate (as in rapid multi-vote), but DS has odd views, so I wouldn't say that it's a good indicator either.

For example, someone could add hundreds to C4 woo ratings in just half an hour. This has been clearly done to Jonas, as he had 4 times as many ratings as anyone after 1 week.

BBOnline and TiBB - more difficult than C4 woo but still VERY easy (BBonline in particular). A sign with TiBB is that voting numbers are alot higher than they were towards the beginning.

Your best bets for accuracy are niche (non big brother) forum polls, that discuss BB but whose main focus is not and require you to register in order to vote. Manipulators are unlikely to reach these, although a downside is that they have much smaller voting numbers.
