There is evidence, not least Solak's stuff in his interview/statement about "well, the intern should have complained more". Not "it didn't happen" just blaming the intern for not complaining more loudly.
I'm not sure what "actual evidence" you are looking for when the club admitted the wrong they've done, they haven't accused the intern of lying when he said to the investigation that he felt pressured and uncomfortable.
There seems to be a group of people that have decided that because Solak and the club have gone through with their "fuck you, we're not sacking anyone" routine that it means the club did no wrong.
Well, they did do wrong. It's not a "narrative" being pushed by Adam Blackmore.
