Who wants to bet that it was something stupid Derrick said as usual which caused someone to take it as truth when it is infact a stupid lie and if he is making it true which he probably does not have the authority to, he is doing it out of malice.
If it's on formspring, you should be able to. If it's on another website, you should be able to as well. If it's from a magazine, book, sticker album, or DVD special content, to name a few, then it's not reliable.
Yes, it was re-uploaded. What you did wrong was not specify a source (we've had fan art based on comics that looked perfectly legit, until a user discovered where it had come from, so, now, I'm more cautious about comics) and uploaded it with an unrelated name. All images' names must be a short description of their contents, in English, so that users can search for them.
