Yes it's an assumption. But it's not baseless.
The feedback you've left him is also an assumption. And also not baseless.
We all make assumptions all the time, including you. There's no need to point it out every time.
Yes, baseless. It is like seeing a guy eating a sandwich, and some one yells "HEY YOU STOLE THAT SANDWICH!" Only he didn't see the sandwich get stolen, he just assumed it was, either because the person yelling doesn't like the guy eating the sandwich or has some issues of their own. Then when asked for proof the only response is "Well it looked like a sandwich I saw stolen before, so it must be!"
Actually the feedback I left Vod is documented fact. No one disputes Vod doxed OGNasty and claimed to have reported him to the IRS. As far as the comment regarding his mental state, I have repeatedly offered to modify the rating and replace it excluding that part if he feels that would make it a valid rating, but he refuses to respond. Vod avoids a direct response at all costs, because he is well aware his actions are indefensible.
