I don't think that is a bad thing in this particular context. When people say deliberately horrible things about other people without evidence, they should be liable.
I also think that should - and eventually will - be expanded to include deep fakes that take the images and voices of other people and have them say/do things that harm the reputation of that person.
It is going to get really crazy with deep fakes.
Each year they will get better and harder to detect.
A generation from now it may be totally impossible to figure out what is going on....
