The Wonderful World of Kenneth Eng

There's normal grade author-crazy......and then there's Kenneth Eng.  Author of a 2005 book about cyborg dragons (or some such)  which he promoted by:

• (2005) Giving Eragon a one star review on Amazon and recommending his own book instead. (Ditto Harry Potter, and probably others).
• (2007) Discussing it on Fox News when he was meant to be explaining why he wrote a newspaper column called "Why I Hate Back People" Then he ended up in jail for a while for threatening to kill his neighbors.
• (2012) Releasing a new book about a haunted aquarium pretty much the second his sentence ended and he was allowed back online.
• Spamming everything in sight.
