User IDs are definitely private info, since they'd allow you to follow a user's behaviour etc.

  "user 1234567 viewed post 89564385943" I can see how that's private info, but would this be: "client x viewed user 1234567's profile"

    Neither are private info. Private in theop law sense.

    Sure, if user 1234567 isn’t particularly popular.

    If the user id can be joined with other data to give a name or similar then it is considered personally identifying in terms of GDPR. I am not a lawyer. You should hire an appropriately qualified lawyer to review your data hygiene practices.
