There are many reasons why an escort may opt out. If I thought I could get away with not having reviews anywhere on the net then I would, for discretion purposes. I have read things about myself on reviews that would make it very difficult for me to deny if someone from my private life should come across my profile, specific details where my client doesn't realise he's compromising my discretion by saying things such as Kendra has a lovely tan from her holiday in ibiza or Kendra had a beautiful apartment at such and such a place or I look forward to seeing Kendra again after she returns from her surgery etc etc etc, it's things like that that i cannot deny should anyone I know see my profile. Then I don't like too much sexually explicit information written either.
There's also the threat of false negatives being written about you from the local competition or local pimps etc.
So there are loads of reasons why a girl may opt out, not just because someone else has written their profile for them.
