I don't know if others are taking the harassment approach, but if they are, I have to remember that their brain is not wired like mine. What to me seems like negative publicity may not seem negative to them. Their audience and marks are of a different mindset. They are not trying to get what we would consider good publicity as they don't care what we think.
In their case, their audience, unlike Klayman's intended audience, may be an audience of one. There are still those that think that somehow sucking up to TFG can be a good thing for them. Either they are true believers or are delusional that they think they can use Trump for their own benefit.
