Not all trolls post comments. I have several trolls that send nastygrams, disguised as emails. I cut back on my posting while trying to figure out what to do with my private trolls. None of them are interested in dialogue. All of them make judgements, projecting me into their life experiences. Some of them seem to be good people who are in a hard place. Some of them are bitter and angry at everybody. None of them know me. Most of them don't even want to know me.
It took me over a week, but I have decided how I want to deal with them. I have a spam filter of my email, and I added my trolls sending addresses to my list of spam. Since I never go rooting through my spam folder, in thirty days, when it automatically empties, my trolls will be gone. Best of all, I will never even know they have been here.
