Way to filter out (IP Restricted) items? (CLOSED) (CLOSED)

I'm sure a lot of people like these items. No problem with those that do. But it really grinds my gears to find an outfit or something that would be *perfect* for a project, only to find out that the reason it is so well designed is because it's taken from a game or tv show or something, and as such I can't use it in my work.

There's a NSFW filter, why not have a restricted license filter as well? Seems like it'd make sense.

More filtering and sorting options are already on the hotlist for the coders, and I hope we can see that implemented soon. 
I have added your suggestion to the open development discussion topic. Thank you for your feedback.
