here witnesses are nothing unless they also have evidence

Not everyone has shadowplay running 24/7, not everyone is recording 24/7. There are cases where witnesses may be the only proof you can have. You could have had a good twenty to thirty people talling you what I'm telling you now. I'd say it's a poor situation if you're choosing to allow reported abuse because of a lack of video evidence. I'm not saying you should ban the guy over circumstantial evidence, but I'd at least consider looking into the situation. If it's your policy to not take circumstantial evidence into account though, that's fine. The witnesses are irrelevant.

You have three videos, and everything I'm talking about is in those videos.

If witnesses are the only proof you have then don't post. Simple. They can't convict without proof.
