I am just trying to take a stab at this..... (*because the question was a bit confusing to me, sorry*)

When searching reviews you can search by email address, there isn't actually a place for an ad link or ad site but you should have the email address or phone number as those are usually the two ways in which a hobbyist contacts a provider.

In regards to the EROS direct link, most of those will have the email address or a phone number. By utilizing one of the two you should be able to do a review search.

I hope that is some help, if not sorry I tried

Copy the last part of the URL (something like "cr-ibt1-victoria3.htm"), and try searching on your regional board.  Many times, someone will have asked about the provider (or given up some information), and you can catch up on what's already been said.

right click on pictures and go to properties.
