>>86358193??? Most of this is obvious or exaggerated
>Sex jokes require a sex themesHaven't seen anyone get in trouble for this, but if you're making sex jokes your stream should be labeled as 18+ anyway because you're not family friendly
>Loli and shota vtubers can't be lewdNo fucking shit retards
>Loli and shota vtubers are subject to Twitch's Youth Safety guidelinesHas this happened to anyone? Have never heard of it
>Exposed hip, underboob, etc require sexual themesYes that's all listed in the TOS and is not an unwritten rule
>Art or promotional graphics includedHaven't heard of this happen to anyone so I don't think this is even true. A piece of art has looser guidelines, but as soon as that art is rigged and tracked it gets treated the same as a human so additional rules are enforced. You could argue this is retarded and I would agree, but that's what they've said so it's not "unwritten"
>Exposure of feet, tongue, etcThis isn't simple "exposure" like the OP is saying. This is if you're making it the content of the stream. If you're just in a room and barefoot then nobody's going to care. If you're putting your feet into the camera and keeping them there then you're basically providing feet jerkoff material for the audience and that's where the line is drawn. Same thing with twerking and having your mouth wide open with your tongue out for an IRL ahegao
