That is incredibly saddening to hear, and it's so frustrating and upsetting that creators getting harassed to the point of orphaning their works and deleting their accounts has become so commonplace. It's very not difficult to stay in your own corner of fandom and ignore tags/content that aren't to your taste and leave others to their own corners! Especially when it's minors poking their heads in 18+ spaces and yelling about what they find. :\

I hope the author is okay, and finds some peace moving forward. ):
