No SP's have responded so from our point of view: Do not follow her! Forget you ever saw her. Personal- anything- including social media is just that, personal. You can follow anything that has her professional nom de plume but if it's under any other name than the one she uses for escorting/etc you're crossing a boundary you are not expressly permitted to cross.
If an SP wants you to follow their personal social media she will tell you, finding it accidentally is not expressed consent. So be respectful of her boundaries, her right to have a personal life, and her privacy and maybe one day you'll get the OK.
And think very carefully before you bring it up with the SP. Maybe you could ask her, but would she uncomfortable if you told her you found her private profile? Personally I would, and I would think twice about spending any more time with you if I knew you had been lurking on my private media. Maybe not everybody will be, but since there are SO many social and online options to get to know an SP you don't need to follow private media as well.
There are many more implications than simply 'it might make her uncomfortable', does she have a civvie job? Does her family/friends know about her escorting? Is she following her landlord or her employer? Your presence in her social media
could have a serious negative impact on her life.
Lastly, boundaries are necessary for all of us. Just because something might not impact you negatively doesn't mean it won't have a negative impact on the other person. And trust me, she will be happy to share more with you if you respect her boundaries and let her decide.
Cheers!
