I'm going to spam a hacker
That sounds risky. Why are you going to spam him?
He keeps annoying others with his hacking
It is good that you identified a hacker. But you should leave things like that to the authorities. Report the person and move on from him.
I'm going to do it anyway.
I believe you need to let the proper channels handle it, because you never know how strong this hacker can be. Do you really want to risk your information, your finances, and your family for this?
