I doubht there is any such feature at the moment, though it might be possible implement by building on the existing "bad image" feature, effectively turn anyting labeled with a "fair use" template into a "bad image" with regards to the User: namespace (and others). You can't hard code this in because templates change, new are added and so forth, but a list in the MediaWiki namespace of "blacklisted" templates (or categories if that is easier) might be doable.
In the meantime someone with toolserver access could relatively easily make a bot that automaticaly remove anyting "fair use" from userpages, userbox templates and things like that.
I have a report page that lists user pages sorted by the number of fair-use images. (it might take a while to load)

A synopsis:
241 [[User:HeraldicBot/Gallery]] 229 [[User:Gram123]] 226 [[User:CyberSkull/Images/Icons]] 208 [[User:Cburnett/Images]] 181 [[User:CyberSkull/Images]] 176 [[User:WolfenSilva]] 143 [[User:YUL89YYZ/images/DVD_covers]] 119 [[User:Palm_dogg/Images]] 116 [[User:Electionworld/worldwide]] 112 [[User:Johan_Elisson/football_badges]] 107 [[User:Dlloyd]] 100 [[User:Cyde/template_check]]
Most of them are "a list of everything I'm uploaded". It's fantastic that they've uploaded so many images, but it would be still better if all fair-use [[Image:...]] were turned into [[:Image:...]] links. Do these look like the sort of things that should be changed by a bot? Given how helpful these users have been, I would be more in favor of discussing it on their talk pages first.
(for what it's worth, I'm counting any image on en.wikipedia.org that's under Category:Fair_use_images, which contains 112 subcategories. I think that's the slow part though)
