I'm asking because I've had people who post hyper-critical comments and yes I know of the the "Ignore" feature but I just rather not have them leave nasty comments. If they don't like the story then they shouldn't read it.
So I gave the user who most likely sparked this comment a check and holy fuck I need to recruit the guy for Marcie and Gina reads lol Yeah besides ignoring there's sadly not much you can do. I do believe it's possible to report a user for harassment if it really comes to that, but even then they might just make an alternate account out of spite. If it's obvious a comment is written in bad faith I would suggest to simply not engage. These guys crave attention, not giving it to them is better then any response you could write.
