The issue is that no one knows who posts the truth and who posts exaggerations or lies. People can sometimes have a personal vendetta that is rooted in emotion or even idiocy. I imagine that the app isn't exactly set up to vote on assertions with personal accounts, to allow the truth to emerge.

I will tell you a very simple way to avoid cheaters if that's your goal. Look at their interests. Do their interests involve meeting people and doing lots of social things? Or are they more of an academic type? If they're the former, odds are they will cheat on you eventually. I basically told my partner directly that it's impossible for any man to truly promise that he will never cheat, but my interests make it extremely unlikely that I will, and she was okay with this assertion.
