I don't know, I try to get things worked out with people. Sometimes it works, sometimes they just get more angry.
And sometimes they just demand you agree with them first - at which point one might as well give up talking. The ignore thing is useful, but then someone replies to them and you're left wondering what the hell they're referring to. Just as easy to scroll past the offensive people.
Or they don't demand that but it's what you think they said. Words on a page are written and read through our filters and we don't all have the same filters.
