Eh.
Jules and DD are into things the majority of people would find gross or disturbing sure, but I wouldn't say that alone is enough to call them amoral or that they somehow betrayed the trust of a bunch of viewers of a let's play channel. I'm not even posting this stuff to "get" at them or air dirty laundry or whatever, it's just a bizarre and perhaps even more "real" side of them that makes for some interesting conversation.
I can't stop anyone who does but personally I wouldn't because one of the big determining factors of being a "lolcow" is having an enormous lack of self awareness, whether unintentional or a willful ignorance so you can demand that EVERYONE accepts or participates in your version of normality. Julian and DingDong both know their shit smells (DD especially har har) and keep it in circles where it's enjoyed or accepted, and they're certainly critical about furry as a "lifestyle" if this clip is anything to go by.
Hell, just look at how much Dingdong covers his tracks compared to Julian, to the point where most people only know him as an alias and (to my knowledge) any solid ties to his other identities are torched and burnt. He's started and deleted several accounts for his tuba stuff and I can't help but feel some sympathy for a guy who just wants a corner to discuss and get their tuba fix. Then again I'm the one digging up and sharing said tubashit so maybe I'm a bit of a hypocrite.
