Hello there! We use IRC channel on VSTF wiki. There is a bot responsible for detecting unusual edits and listing them in the channel. While his/her edit is published, it's detected and listed by the bot as well. Therefore I undo his/her edits and report this issue to VSTF.
The only acceptable sources for images are the DVDs, iTunes or Amazon Prime downloads, the official YouTube channel, Hulu, Netflix, Nick.com, or any other source that legally plays or allows you to own the episode/movie/short.
