illegal use of debian logo ?

[Jacques MICHAU <jacquesmichau@yahoo.fr>]

I was browsing a hardware web site, full of ads. My eyes stopped on a 
banner : http://www.monsieurprix.com/images/pub/multepass/1.gif

For sure, this is the Debian logo (I have display problem with Firefox 
with this GIF, it's okay with other browser)
I checked on the www.debian.org/logos : the logo can be used freely by 
anyone if the logo is related to Debian, which is not the case.

Is there something to do ?

Please, keep me informed if possible. I'm curious about that kind of 
legal abuse and what can be done.

Have a nice day
