Me personally I have always been one who can not only dish it but can take it just as well. I get a laugh out of the over the top "Your fucking sick" or "Worst author ever!" cracks. I mean what else can you do but laugh at them? If you take these types seriously you are going to get no where.
This is how Master and I dealt with comments made to one of his stories. One person posted "Klingons with fur." We both laughed at that one and just shook our heads and moved on.
The crowning glory was Master then used that line "Klingons with fur" in his story as a poke at the person. When I read it I just about fell out of my chair laughing!
Another person on the same story posted, "r u a muzzie?" Amusing at best. I'm still trying to figure out what a muzzie is...
It makes me think of that rhyme we all learned growing up..
Fuzzy wuzzie was a bear, fuzzy wuzzie had no hair, fuzzy wuzzie wasn't fuzzy was he?
