I'm not saying that Patrick S. Tomlinson isn't fat and stupid enough to try but there's nothing he can do to stop you from writing and publishing anything about a "character" named Patrick S. Tomlinson based entirely on fat and stupid Patrick S. Tomlinson. After all, it's literally all not true, stalker.
The fat idiot doesn't "own" the content of his tweets to where you can't put it in the mouth of a "character" but I would love to see him and the SWFA try to claim public tweets are copyrighted material that other people can't republish on a whim. They could bitch to Amazon and get it taken down maybe but that's just Amazon's ability to curate what they sell. If this fat faggot wants to go to court to argue that taking the content of his own tweets as literally true to mock him is defamation, and the SWFA wants to take on that burden, then I couldn't imagine anything funnier.
Standard disclaimer that this is not actual legal advice, et al.
