I was a Youchew member from mid 2017 to early 2018. I created the account back when I made YTP for the purpose of hosting a collab. It gained a fair amount of traction and it did pretty well. I took it off youtube as apart of some purge about a year or two ago, but that isn't too important. Through this collab, I was able to network with people like Paperking99, NKpower and some others in that circle.
Youchew was in a much better state then, because it existed, but still definitely garbage. Echo chambers, harassment, and people giving out waayy too much information about their lives than what should be on a forum supposedly about Youtube Poops.
I was going through a phase at the time, and if I didn't get out of it, it is certainly possible I could have been a trooned out furry retard or neckroped. Youchew is definitely, and still definitely, a refugee camp for autists, impossibly manic individuals, and troons who all liked YTPs. There were other YTP sub-communites, the Micheal Rosen community comes to mind, that weren't nearly as fucked as those people at Youchew.
I remember a dude at some point wrote his suicide note on Youchew and you had like 45 replies of people trying to talk him out of it (myself included). He didn't end up going through with it, but it was quite telling of how fucked people on Youchew were, cause to me, I wasn't very surprised that this had happened. This was kind of the point where I realized I had to get away from the YTP community.
Biodegradable, while harmless on his own, is desperate for acceptance from the OG YouChew crowd and will rigidly agree with anything they say.
Definitely, while I don't have any proof of it, as I haven't been in a discord with Paperking99 and/or Bio in a couple years, there was a lot of instances of him kissing Paperking99's ass (who was popular by YTP standards, and had a large crowd of people seeking to befriend him and/or please him on his discord). Again, I have no proof, so take it with a grain of salt.
