Peter,
I agree that there are people who don't follow the rules and there is no real way to enforce anything. Of course the people in the know realize that there are ethical and unethical breeders.
In this country, our major problem is this "farm" in Ohio that produces millions of seedlings which they sell indiscriminately through the big box stores here. This is where our "unknown noids" often originate. The sad thing is that it wouldn't take much more effort to propagate some of the better cultivars and sell them.
Maybe this all speaks to again forming a Sempervivum society of some sort so that we could have somebody keeping track of the names. The problem with both the Sempervivum Society and the Sempervivum Fanciers Association was that there was essentially one person running and doing everything for both groups. When they stopped, so did these societies. For a society you need officers and a board.
OK opinions on that!!
Kevin
