He likes to slander individuals who he has come to hate.
I was one of the individuals who ended up on his "hate list", because people he hated posted on this forum.
He buys domain names and starts small websites with the aim of defaming those he has a grudge against.
When he hates someone, he does everything in his power to harm the person's living situation, reputation, income, family, etc.
He is a very sick man and a pathological liar.
