You should be proud that you have limits, if I saw something interesting that has no source, I'll take my time to found it why?, I have plenty of spare time and I know how to search , because it could be good or it could be like this thing, so I don't know if it's off my limits, I'll take the risk for the sake of people who wants the source ... and then regret it .
Look the stickied comment, I put the link to it if you want to see it, if you're into that I think it's ok, if you're not, prepare yourself because it's gonna get weird.
