Rate me late if this has already been brung up but it’s nearly a 200 page thread.
back in one of their mine craft videos Gavin put up a sign saying “Ryan the baby anus guy” which was censored in the video but was confirmed to be what it said (I’ll find sources soon). This coming off the back of Ryan making some mention of having to put your finger in a baby’s ass to clean out the poop properly. His whole persona in Achievement hunter always had creepy predator vibes
Edit: can't find a lot because this was back in 2014. But at their second panel for rtx 2014 Gavin wore a "Ryan the baby anus guy" shirt
Down in the comments someone even mentioned "don't shame the family bit" as well.
