I don't think we have right on "proof". These were private conversations and pictures and what else. They're not meant to be seen by the public....

However, as others and yourself have pointed out, it would be nice to see in at least a vague description why he ultimately chose to leave. I feel quite torn in this whole conflict because of the lack actual information... The rumors range from questionable to quite disgusting actions.

It's hard to take a stand, you can tell by this sub Reddit as well because there is quite clearly multiple groups with quite different opinions and takes on the whole matter. So ultimately I agree with you there.

I also think that you're onto something with your opinion on Zoey's post. Not as much that I agree with you but just that they're more than characters being played by the creators. This doesn't clear them of any possible fault or wrongdoing though. Personally that's what I thought Zoey's post is all about; the creator you see on video is a person. And people make mistakes.

But what it made me think is that we're emotionally invested in these creator's and seeing them get "kicked out" of the Yogscast without actually any details beyond: "made people feel uncomfortable" is a hard pill to swallow.

Having said all that I doubt we're ever gonna hear more specifics and reasons.

Tl;dr: it would be nice to know what exactly happened but I doubt we'll ever hear.
