Thanks. A friend of mine actually showed this to me a few days ago. 9GAG is a popular site where people can post memes and other things they find interesting from all over the internet. I don't think it's a case of anyone trying to steal it but just sharing something they thought was cool. The 9GAG tag is on all photos posted to 9GAG and my signature is visible, so I'm not too worried about that. Plus a few people in the comments gave the correct credit. Thanks for looking out, though. I appreciate it.
