One of the main reasons why I even checked IP (I normally never do that) is because the pic posted here was posted before and the crew tried their "delete that post now" spiel yesterday, for whatever reason. Could have been them, and of course that IP hash could still be them, I do not know that. If it is the GV, then I think it's unlikely.
Is it good to know that this pic was at least posted by that IP hash or not? I think it is, that's why I checked and posted about it. Normally I wouldn't care, and it wouldn't matter, just as you said.
Shills like the one yesterday with the fake Biden pic used a new IP. I also checked that when it was obvious that the pic was fake. Smart shills do that, and thus IP checking is useless.
