Text on profile indicates a poor attitude and contradictions. She says she only BBs with her partner, which most will read as she has a partner, unless she only BBs if/when she has a partner but doesn't atm.
She does, after all, say she is open to being a SB but also wants a boyfriend but at the same time as advertising as an escort. Whatever, the situation, she'll be having sexual relations with other guys while barebacking somebody, who also may be shagging others, possibly without protection.
The profile dates from 2018 but isn't familiar so it could be this SP was elsewhere or the profile could have been dormant and recycled. More likely the later as the photos from the one review linked to the profile are of a totally different girl. This shows the importance of including photos, so well done to Sinz for posting them to the review thread.
So, no intel, just gut instinct. Lots of red flags as you say, so not sure why you're still interested in her.
