This is what is confounding about this. This account/device, has only interfaced with youtube for purposes of a friend's music. The only things it has done is watch his channel, and upload to it.

Had it been on my account, I could easily see how clicking on links with terms like furry in them, on places like lemmy, might lead to something like this. However this is a device, and account specifically created to have only "clean" history when interfacing with this account. Also, it would have been blocked on my account, but using a creator account with ad block on can get the account banned.
