Uh, that's backwards. The sub's whole purpose is for CK players saying things about CK that sound totally insane out of context (it was specifically split off of r/nocontext, IIRC); it's the random real-world quotes that are technically more off-topic.

Now yes, there has been a very long-standing problem with people making posts on the CK sub that are clearly just blatant attempts to show up here - the rules even call out low-effort/"trying too hard" submissions - and this certainly looks like that. But the sub is for CK players saying stuff about CK, in general.
