User pages have no copyright exemption. We should root out and destroy any such examples, regardless of whether it'll piss people off (although we should, obviously, try and be nice about it - in most cases, people aren't trying to deliberately cause a problem).
There has been 'de facto' tolerance of unfree-with-permission images on user pages; I think this should go, too. If you're not comfortable with putting pictures of yourself, your family, your dog et al. under GFDL or another compatible license, don't put them on Wikipedia even for your userpage. After all, you could say 'Go to my personal web site for more info about me', or something - links are perfectly fine.
