Actually, you were not one of those that I had in mind but one member "outted" himself and yet another I suspect is a dealer of not only sailboats but other R/C boats also. One has been contacted through a PM but the other hasn't, ........ yet.
I give most members a lot of space and understand that when they do signup they don't bother to read the site's rules as they assume that all forum site rules are pretty much the same but no, this one throws in a few extras. I'm the first to admit that when I first joined I assumed this also until I took the time to read them.
There are ways to publicize your products if the rules are read and the author understands them. They shouldn't look at the rules as a bad thing unless they're trying ot be sneaky but can also find that it can be a way to get yourself noticed by prospective customers.

OK, where were we?
