Some want attention - they want your reaction, often your overreaction so they can make themselves look like a victim. In these cases, ignoring them for a while will probably make them move on to the next target.
Some want power - they want you to look weak so they can look strong. They like the feeling that you can’t do anything to them. Ignoring these will make them continue. Here you have to fight back.
And yes, usually you don’t know what your bully wants.
This really depends on the bully.

I find that the ones that want attention don’t particularly enjoy being punched in the face either.
Yea, it’s really a 50/50
