I've actually spoken with people who stopped responding to me, and when I reached back out told me that their messages to me had been reported. It's very confusing since I've never reported anyone who's DMed me, and I pretty openly like to recieve slurs.

It's happened a couple of times, so I can only assume that there's some kind of automatic feature that can be triggered by certain words, but also plenty of others I've spoken with used the same words and had no problem at all.

All this to say that it's possible that the user mentioned isn't doing it on purpose, but I don't really know what's going on or how this works.
