I think you're off base here, but what do I know.
There's a better version of that meme, BTW. (Thanks to anon who made it.)
If you're going to look for timestamps during a video, you have to say which video.
>Basically, the whole back-and-forth about the image files for the meme seems VERY suspicious…
Well, I'm the Meme Farmer and I was half of that dialog. I was trying to help an anon who seemed to be clueless about how to use the chan. When capping memes I always hope to get one that's a decent resolution and the first one they posted was too small, so I asked for a better one.
I agree, their reply to me was quite strange and unexpected, almost off the wall. Who cares what the image hash is.
I guess I decided to stop talking to them, after the strange response.
Hope that clears up 50% of the mystery.
I can't speak for the other person – no idea what they were up to.
