If you want to get them banned or at least have them punished, make sure you send video recordings of them saying the things. I don't know if you play a lot of games, but in almost every single game they don't record their voicechat, so the only way someone can get banned if you use the xbox report system, is if 10 people report it within a week
(It's different for each game but for something said in a voicechat, because it's not recorded you need to have many people report them for the same thing in a short amount of time in order for them to get banned)
I would recommend recording these encounters then going to the forums and reporting them with video proof. That way they'll get banned because there's proof, if you don't do a forum post and send video proof, nothing will happen unless you get 10+ people to report them with the xbox report system for harassment.
I even try to reason and get an apology from those that do it and all I get is even more abuse back.
There's no point, while I do agree that this kind of thing sucks when taken too far, there's nothing you can do about it. They're only saying it because it's online and you can say whatever you want online without any physical repercussions. If it happens again I would suggest muting them, in adventure mode if you want to mute someone, you go to other crews then click mute other crews There's not a reason to talk and ask for an apology, because they're never going to give you one, just let them dig their own grave, record, and report.
To reiterate, if you want them banned record and report on the forums, reporting someone using the xbox report system won't do anything.
