That doesn't pass the sniff test, many other pages on knowyourmeme correctly attribute memes to 4chan.
If you were right that would be easily verifiable. Do you have an example of a post dated before 2018? Maybe you're getting tricked by the fact that 2018 was 8 years ago?
I think you are taking their point literally, its not that knowyourmeme is not crediting 4chan, its that the racism/edge is polished off presenting a more mainstream version of many memes.
