Webfont Blacklist

I'm regularly stumbling upon websties which are using webfonts from which I certainly know that they are not available for web-licensing yet. Or in other cases I see poorly rendered versions of iconic typefaces and the CSS tells me that this must be FontSquirrel outputs.
How should I address this problem? Playing police and reporting this to my type-design colleges?
(I might do that, if they are my direct friends or employers, but for the rest I don't like to be this guy.)

Shouldn't there be a kind of blacklist where such websites can be submitted?
If interested in hunting violation, foundries could browse through it themselves.
This might also create some awareness under web-developers who mostly are not interested in such "boring" details but rather discuss workarounds:
