Advertising on other grids

I’ve had some other grid owners message me recently to complain that some of our users are advertising DigiWorldz services on other grids.
While we appreciate your support and enthusiasm for DigiWorldz, we’d rather none of our users do this.

We don’t mind if you post in appropriate Social Media Pages, Blogs, and other web sites, but we’d rather you not do that on other OpenSim grids.
We feel a responsibility to the other grids within the OpenSim community to not do this as I do not believe it’s fair.  They are trusting our users to visit their grids without fear of us “Fishing” for their users, and in turn, I hope they too feel this sort of responsibility towards DigiWorldz.
