A list of "bad guys" could be effective, but Dave is right; a "good guy" today 
can be a bad guy tomorrow.  Also, where do we draw the line?  There is a major 
difference in kind between a ham that buys a device, installs it in his or her 
own home and has S9 noise to an antenna close to the house, and S9 from a 
device in a neighbor's home.

I would not use the absence of a device on a "bad guy" list to eliminate an RFI 
source. Even a good device can be defective.

The problem with such a list is that there are literally tens of thousands of 
devices marketed every year, so no list is going to be more than a small sample 
of what is out there.

I suspect this would be a futile effort in the long run...  Why?

Given that most companies are always looking for a better price on all
subassembly's-- like power supplies, what is clean today, could become dirty 
tomorrow...

This would force the list maintainer to constantly recertify all items listed.  
This is not a scalable solution, and as such would be worse than no list, in 
that one might think a device is clean, when it is not clean, and bypass the 
RFI check of that device, when looking for a source...
