Just had someone leave me a couple dozen nasty comments and then mute me right after. Very little of it was constructive, most of the comments flamed my story, my MC, or insulted me personally (they talked about how ugly I must be a few times).
I deleted most of the them, reported a couple of the really disturbing ones, and muted them back. If you're following me, there's a chance I've got your story in my reading lists somewhere, so just be aware they may have found your book from my profile and could you next.
If you'd like to go ahead and mute them now, I left three of their comments (the most constructive ones) up on the first chapter of Five Guys and a Funeral. I can't see their name or profile, but they are the most recent commenter, and one of their comments talks about how "happily" should've been used and another talks about how the reader how no reason to believe Jasper is kind and intelligent and there's too much telling. Hopefully that's enough information for you to find them if you wish!
I also have a screenshot of a couple of the meaner comments, DM me if you'd like to see that.
