Tony the Tiger debuted in 1952 and has appeared on every box of Kellogg’s Frosted Flakes since, it's a well established trademarked mascot, which dethroned Standard Oil's, later known as Exxon, little tiger mascot that they introduced in 1964. See Exxon Mobil Corp. vs. Kellogg Co., 00-252.

Youtube's rules are clear; "Trademark infringement is improper or unauthorized use of a trademark in a way that is likely to cause confusion as to the source of that product. YouTube policies prohibit videos and channels that infringe trademarks. If you upload content on YouTube that uses another party's trademarks in a way that is likely to cause confusion, your videos can be blocked and your channel suspended." You'll find similar terms of service agreements at the other mentioned social media sites, which is how I guess those channels got taken down. There's parody and then there's not so obvious parody.

Jani Leinonen owns the Tonyisback.com URL. He's a Finnish artist, not a commercial artist. In 2012, Leinonen and two other people were sentenced to 60 days fine for fraud and forgery , as they had stolen the Ronald McDonald plastic statue from McDonald's, which they later destroyed.

I keep telling you guys, Finland is the wild west of the northern countries. BLESS THE CRAZY FINNS.
