Dissecting that image: there is nothing even remotely resembling 'evidence' in it, aside from his own alt profile posting the link to whatever nastiness is there. The snips are altered (one is clearly enlarged) posted out of order (you can tell from the reply lines) and there is absolutely no reference to which discord server(s) they were taken from... without the entire, unbroken, and unaltered conversation this is nothing more than a collection of out-of-context snips, possibly from multiple conversations and multiple Discord servers, served up in a mosaic. No logs, not even screen shots. The only individuals represented in that pic that could possibly be associated to each other are the ones responding to one another, and there is no possible way to solidly associate those individuals with anyone on Itch.io, because as far as I know there is no way to link a Discord account to Itch.io like you can with other media accounts. In no world is anything in that image even moderately convincing 'evidence' of any kind-- it only demonstrates a wholly unhealthy obsession on the part of the person posting it, and a malicious intent to damage the reputation/image of anyone they perceive as an adversary. Ordinarily, something like this is cobbled together to look at least a little convincing... this picture is just a disjointed mess.
