Yep, as Zorlun had pointed out, already from some time, their terms and conditions for creators said they could go and check elsewhere - not being for now a game creator (and anyway at least the first would be released without any Patreon or so on), I never read them, it is even possible it was already like that from many years, and not only in the last couple of years.
In some jurisdictions, if I go try to find out e.g. your facebook account, your linkedin account, but even your discord account or your account here, even if they are under different logins, and then try to use that information to bully or harm you, it can be considered "stalking", but I am pretty sure Patreon makes you accept as jurisdiction California, USA, where they are based, thus being a private commercial contract they can do it.
Do not forget the "Disney effect", many (I would say most I know of, but I am not an expert in the matter) of the girls that worked for Disney as adolescents for TV serials and as singers, as soon as they stop being under contract switch from "daddy's little princess" to "sluttiness role model" (to the level of saying explicitly "I fucked everyboyd from the director to all the production technical staff", even roughly with those words, publishing plenty of sexual pictures on OF and other media, etc.).
While they are under contract with Disney (based in California) they are in theory forbidden to do anything that can become public and could damage the "little girl pure example" model - the point being that Disney in practical terms regulate their personal (specifically, sexual) life, even if indirectly.
If they can do that, in a way it is not a surprise Patreon's behaviour.
The ironic side, is that Hollywood is where the "casting couch" approach was used in the past (but to no offense to the "metoo", also to the advantage of actresses whose major selling point were definitively not their acting skills ;-)) and certainly even in more recent times
