Read the rules
Explicitly banned
Is it?
22 Privacy of service providers
It is generally not allowed to post personal info of service providers, such as real names and personal social networking profiles and photos from messenger providers like WhatsApp.To clarify, this means no personal photos at all from anywhere. Phone numbers may be posted in full if the number is online on a current advert. Personal numbers not allowed. Hotels may be named but not room numbers.
General description of in-call locations is acceptable, but not specific house numbers and/or street names.
Modelling, porn, and media-related work are acceptable to be posted, even if it includes their real names as they actively sought publicity / higher-profile. Any news items may be posted. All aforementioned restrictions do not apply to thieves and those with criminal convictions. Past name changes are never censored, regardless of reasons.
Many escorts have promotional social media presence as escorts. How would posting links to say, Hayley Hazard's social media sites contravene the rules? I refrain from linking to the social media of escorts like HH just to be safe but frankly there isn't any issue at all is there?
Clearly its unacceptable to link to an escorts personal and non-work related social media but there ought to be a distinction between social media that manifestly relates to them as an escort and their private social media in terms of what's permissable.
Ultimately its up to the site to decide but I don't think Rule 22 is as explicit as you state.
