Very similar to the Christmas 'ElfYourself' site T&C's actually, although that one had a friendly wording version (ie. plain english) - which said clearly stated something like: "we can use your mugshots and modify/change them for any purpose, including advertising products which you may have a moral objection to."

So, both Facebook and the ElfYourself site could use your face, stick it onto a nude body (rather than an Elf!) and advertise some Adult content, if they so wished.

Surprised no-one has complained about this before then...

Actually - found a copy of those T&C's on a blog post @ http://andyriga.wordpress.com/2007/12/06/elf-yourself-a-merry-christmas/
