I was thinking that it might be a good idea to start a node specifically on what Perl sites to avoid.

I think it's hardly doable since a "Perl site" in your acceptation is quite about any random site that may deal with Perl. There are just too many of them. Of course one may think of at least create an "Hall of Shame" with a hit of the very worst, possibly along with some comments. However I can't see a terrible usefulness in this either, since the sites we're talking about are those that may pop up following a random Google search and the kind of people who may easily be fooled by them are highly improbable to check the HOS first. But if anyone has his or her entry to contribute, I think it will be ok. At your request, I'll move the "main body" of the post in which I commented some of the site's text to a new meditation.

I am sure that there are other sites out there that are just as bad or worse than the one we have been discussing.

There are certainly much worse ones.
