Dear Sir / Madam, 
Yesterday, my close friend (Simona Simova) was contacted via fake Facebook profile to be informed that she has a profile on a escort website. While researching via the German phone number used in the advert, we have came across more ads. These profiles are created without her permission and she is now very upset. 

Here is a list of the profiles we have found: 

- https://escortsofia.info/de/sia-11/ (5.45.68.189)
- https://escortsofia.info/de/eleonora-8/ (5.45.68.189)
- https://escortinberlin.info/eleonora-3/ (5.45.68.189)
- https://escortinberlin.info/sia-2/ (5.45.68.189)

We have already hired a lawyer in Germany who will escalate the issue to the authorities.
