Look, I’m just trying to point theses out. Here’s what people are doing:
On Monday, they pull off a few funnies from this thread. On Wednesday, they post them back to the thread because they can’t remember that they got them FROM this thread 48 hours ago. Rather than go out on a search engine to find original material, they just keep going back to their saved images. It’s “easier” that way. Also, it wasn’t possible that they got them off this thread (even though it’s the only place they go for funny memes.)
Human nature is very predictable, sadly.
