YES! Mute; Block and report if evidence of bad intent is found.
Susan Wheelright recently wrote that there has been a ton of stupid actions and anti-actions by so-called "readers" lately. One of my actual buddies, Alan Asnen, had his account suspended thanks to one of these trolls.

I had one drop by and accuse me of using a word in my story as click bait. Quickly muted and blocked.
My partner thinks that there are some dedicated troublemakers around who make it their business to hassle people.
