Ugh. That's never fun. Can you not answer those comments at all? Just leave them?

Sometimes I have people go through my body of work, leaving comments like confetti. I don't always answer all the comments because, well, I have a large body of work, and sometimes I just don't feel like responding. And sometimes I just don't respond to someone who's an asshole in the comments; I just reply to every other comment and leave that one standing out like the proverbial sore thumb...
