This is a horrible situation.
My advice (hard as it may be) would be the following:
1) Take a break from independent work (maybe 2 months and delete your AW profile). He will then not be able to track you.
2) Work Agency or Parlour.
3) When you re-start on AW, work in new areas and completely ditch your old destinations (this is the difficult part as it pushes us out of our comfort zone and you lose regs) but I think it’s necessary.
4) I agree with your idea of wig, adding tattoos, photo blurring etc. I would change hair colour completely and make sure my pictures were taken in such a way that they bear no resemblance to your previous pictures.
He’ll have a very hard time finding you if you completely reinvent yourself (I hope).
Remember that you can take ‘body part’ pictures and not show your full self. I don’t mean intimate, but say legs, bum and the like.
If I was in your position, this is what I would do. Also, I would not advertise exactly the same services (you might need to get creative).
I honestly believe you will come out on top in the end.
Wishing you the best of luck x
