Anyone hear if she’s available at Exottica? I see she’s on TLC but not listed as available at Exottica.

Have you called Adonia and tried to set up a date?  Just because they are not listed as "available" doesn't mean that they are not.  

I came across this:

She's currently available only through Perfection Models, I'm sorry to say.  If you want to know more, search this forum for more information about Perfection Models, or PM me.

Adriana Chechik appears to have an escortbook.com website (https://adrianachechik69.escortbook.com) along with a Sitter account (@adrianachechik) that's been active since September 2019.  I wonder how legit that is - the rates are certainly at typical porn star levels.

Chechik (or someone pretending to be her) also has an escortbook.com website and a Switter account....

Based on my experiences, I would't trust anything on switter.
