The problem with these meme spammers is is that they clutter up a perfectly good thread very quickly. It becomes annoying to read and people are baited quickly into responding to them. Especially when some fool posts a meme saying "you don't say" with some dumb reaction image plastered over it. This quickly derails the thread and turns it into a flamewar, which is completely the opposite of what you're trying to achieve. Especially if it's in a thread which discusses the dumping of say Switch keys.
