They do realize that anyone with a smartphone can look up the name attached to their call sign?
"Dave, I want a divorce. No, you don't get custody of the kids or get to live in the same state with us. I filed a restraining order this morning when I filed for divorce. You're a sick man. Get help!" Or something along those lines.
Then again, people sending stuff like that probably don't have spouses or kids. Or it is some kid playing with the old man's ham station.
