When a user has a -ive tag, I mostly read first the feedback before deciding to make a reply or quoting them. If they were tagged as a spammer or account farmer, I don't bother replying to them unless they mentioned something "quite interesting" which I highly doubt that it will happen as I expect that I won't even make an interesting conversation with them.
By a way of checking if some of these users were tagged without genuine reasons.
It would be better to let them address their own tag/s or feedback/s by their own for now.
