It's the nature of the beast when it comes to Eros.  I don't know why other hobbyists feel the need to spend time deciphering whether a provider advertising on Eros is the real deal or not.  Check her reviews.  If she has none, you're likely taking a gamble and adjust accordingly.

If you want the real thing, stick with well-screened providers.  Saves you time and a lot of grief.
