malicious "subscription" websites and GPL

[Michael Keppler]

Hi all,

I'm one of the TV-Browser developers (tvbrowser.org).

We recently found that the German website opendownload.de hosts 
thousands of popular downloads (including TV-Browser) which you can only 
download by agreeing to a 2 years subscription for 96 Euros per year. 
All that written with little fonts, light colors and other things you 
expect from a bogus website tyring to trick you into something you don't 
really want.

We are quite sure that we (as developers) can not do much about the 
"subscriptions" that people may get into (unwanted).

Nevertheless we don't want our software to be connected to such a 
malicious website. As the TV-Browser software (and a lot of other 
software) is described there as "freeware" without mentioning the GPL, 
linking to it or providing any source code, does anybody have an idea if 
we can use that as a legal argument to stop them providing our software 
(and maybe others, too)? And even if so, how are the chances of 
enforcing such arguments in reality?

I guess this question is a bit different to the "usual" violations 
discussed here. If I'm completely wrong on this mailing list, please 
guide me to a better place to ask these questions instead.

Ciao and Thanks, Michael
