I've seen a lot of japanese vtubers with blatant earlick ASMR and they seem to follow this formula:
>Some kind of sign on stream that says menu and then lists a bunch of common SFW triggers>The risque stuff only happens for short burst after 30-50 minutes of SFW triggers. >Sometimes its sneaky stuff like they say its "oil massage" but its clearly earlicking/eating >Instead of earlicking they instead whisper/talk with a lisp that sounds like earlicking>Boobs cannot be the focal point of the stream/thumbnail >There seems to be some twitchlike rule where if the context allows for booba then it can be okay like wearing a towel in a bath and swimsuit at the beach and so on.there is some ratio of SFW/risque that youtube clearly allows. if its just sounds that youtube considers to be "sexy" then they spank you but if you have a 80/20 ratio. For the first ASMR streams its better to just stick to common triggers and some soft talking. I am convinced that new channels have way stricter bot supervision.
To give you an idea then Alias nono from v4mirai knows the rules and has dodged the jannies so far despite doing all the ear licks she wants so she clearly is on to something.
