I saw that video in my inbox and forwarded it along, but didn't respond as I was on mobile. You also didn't identify that player as a "racist" when you initially sent. Reviewing the video again doesn't really show me anything to contribute to that. If it was over in-game chat, then you need to report them via your platform's service.
As for the other account, I didn't receive that tag. Not sure why, but it's not something I can control. I'll forward that along now.
Edit: I and others identified why your alt account's tag didn't make it. You tagged the wrong account.
So to address "What's the deal?"
I try to reply to what I am able to as often as I can. Sometimes I don't get notifications for some tags which are not something I can control. Feel free to hit me up again about something, but there's no need for "what's the deal." That diction choice places people into a defensive posture and makes this less easy.
