Pretty comprehensive, but I would add one to the list and recommend most everyone stay away from them.

FINDOM: these are the new group of women who just create Onlyfans accounts and expect men to do cashmeets or send money. Focus is mainly on having men buy them stuff or give money. They mainly operate on Twitter and do not have a website or any reviews. Be weary of sending deposits or even trying an in person session. Good rule of thumb Mistress Ayn pointed out: If they don't have a website, it's usually a bad sign and you must be very cautious.
