I once had an especially tenacious telemarketer (before robocall) who would not stop calling even after being requested to. I put his number into my FAX machine and set the redial to 100. Tied up his line for hours with incoming FAX machine calls. Never heard from him again - good fun! Can’t do that now for the reason mentioned above - the “spoofed” number might be another private party, not the actual robocaller. Pity.
