See the other response to my root comment, it links to a Reddit thread where you can find out who I really am, as he was using my full name to slander me. This is not anonymous internet slandering.
That post was made 3 years ago. People change, and it does not invalidate the way I experienced what happened, even if I failed to articulate it effectively at the time. I only shared it to provide proof of the dispute, not to win sides.
I see that thread also contains people asking for, and not receiving, proof of (now-deleted) allegations.
