Is there a precedent that suggests there must be a reasonable expectation that if you are contacting someone over the internet or phone and giving them money, that person has some duty to ensure their internet/TV/professional/social media etc. persona is the person on the other end of the line? I'm sure many have experienced calling phone support for a product you subscribe for, the associate is "Brian from Wisconsin" but clearly someone in another country. Bit different case as you were not calling "Brian" specifically, but still someone that you are ostensibly paying pretending to be someone else. There were also countless fortune telling/psychic phone lines were clearly Miss Cleo et al. were not fielding the calls, these businesses ran into other legal troubles but was having people essentially play their character on the other end of the line one of them? I assume on Onlyfans creators can assumed to be "characters" to some degree, don't most go by pseudonyms to begin with?
