He's mentioned 9Gag as a meme source of his a bunch of times.
@UncleIroh could be, i no longer actively watch his content... i used to watch him from his very first videos until some time ago when the content just became repetitive and "safe". about two years ago, maybe. anyway, there is really no alternative to 9gag these days so it is not surprising, really.
@UncleIroh i never heard him mention it - ever. 9gag used to be good until gen-z took over, maybe 5-7 or so, years ago. it was slow degradation of the years though. fun disappeared and you could see how it was transforming into a lot of written memes, twitter/ig screenshots. a lot of violence and gore and animal/nature crap. now its mostly politics.
