Now as far as I know you can post w/e image you want as long as it's within the rules and common decency of this forum. You can post others shoops whenever you want, but some sort of credit or disclaimer should be put in shoop threads. Personally I encourage posting others shoops, and more personally I love it when others post my shoops

. My guess, and it's only a guess, is that you posting it like that w/o a disclaimer such as "
I have no idea who made it but it isn't mine" can make it 'appear' that you are trying to take credit for it in a shoop thread. I am just going by what it may appear to others. Not saying you were at all, so don't take it that way. I don't believe you had the intentions of stealing his shoop and taking credit. From what I am seeing it all seems to be just a misunderstanding.
I will talk to that mod and see about changing his edit to appear as though it was you giving credit - with your permission of course. He isn't online now so I don't know when this can come about.
