Reporting bad clients

Is there any site for providers to report sketchy or even dangerous clients, to site admins or to other providers? Not the persons name or anything just like the area they are in and the phone number that they are using.

Eccie has a Forum for the Ladies to do just that.

In the Dakota's it can be found at this link - https://www.eccie.net/forumdisplay.php?f=1401

Each of the other Eccie Forums in the US has a similar Forum for the Ladies.

THANKS SO MUCH!
