Debate.org is one of the worst opinion based websites from my experience.
The polls section doesn't really bother me too much, there isn't anything wrong with it, other than the fact few people use it since it is so buggy.
However, first off, the debates section is riddled with disgusting or just plain dumb debates. Many of the serious debates get hijacked by trolls. Not only this but when a user sees they are losing, they can simply just not respond and poof, the debate ends in a tie. Also, many voters will only vote for people on their side and many debates are rigged since debaters typically have a few friends waiting to vote for them, and many in the opinions and forums sections make threads just so they can insult people who disagree with them.
