I agree completely with Brion. On it.wikipeida we have recently agreed on a proposal to remove all unverified images and also a lot of fair use images (or should I call them fair abuse?). No matter what the upload dialog states, people seems to be struck by selective blindness when it comes to uploading images. I had to put a warning just above the "Source fimename:" box. It's written in red and with a bigger font size. It says somithing like: "Warning: Files lacking an indication of the source and the licence under which are released will be deleted!". Well, seems that some people still are unable to read it (even if they are less than in the past). Is there any way to make the phrase blinking?
I've spent the last three weeks deleting images from it.wikipedia and i can tell you 90% of images are just grabbed somewhere else. You can tell the difference, genuine images are usually bigger in size.
