"viewers see something WE KNOW is copyrighted we cant do anything because we are just viewers" Why not comment on the image and inform the mods? That's what I've done in the past. But I agree, there's so much of this stuff goes on it's overwhelming. I honestly didn't know about "tubes" until a month or so back - I'd never heard of them. Personally I'd go even further and say that art created using the art of others, be it tubes or stock or whatever, be given a separate category. That way the skills of a person who simply cuts and pastes will never get ranked against the person who creates a completely original work from scratch.
