There is a saying ' You are only as original as the reference to your source is obscured' Everything we see in life can be a source of inspiration but to just parrot it on is not originality, I see this alot in my field. The truth will out in the end and these people will realises they have spent all their time copying and not learning how to formulate their own ideas, which of course will be bad for them in the end. I think you must add to the idea or else you are just a 'Copy cat, dirty rat, sitting on the door mat'. In some ways you should be honored because as another saying goes 'Imitation is the greatest form of flattery' .
