Free are not blocking sites ..they are blocking the adservers via DNS..

You could redirect incoming Free subscribers to a specific page..all free subscribers IPs contain "proxad" ..most if not all of Free's domestic French services are routed "out country" via their centre in Normandy..which IDs itself..

example ..my IP ( obscured slightly ) is
aaa**-*-**-***-**-**.fbx.proxad.net

HTH :)

[en.wikipedia.org...]

Free also run server farms, again "proxad" is in the "string"..been mentioned few times in spiders forum here ..
