A good tip is to always end your responses with a random moral condemnation or random degree of the person trying to shill for Dementor Joe. This is particularly enraging for leftists because the whole purpose of the posting/existing is to gain virtue points. They've been going this to us for 5 years now and the turnaround feels good.

Good words to use "Disappointed in you. Problematic Speech. Calling you Out. Immoral. I can't believe you think that way." or just call them "Sick." an occasional "I'm ashamed of you is useful as well"
