Having seen @Devrex and @Derp in action, what I'll say here is this: if @Sunny came to them and said "My abusive ex-husband is on the game," well, no action was actually requested there. Ok, yeah. He's a piece of shit, but that's just information being offered.
If Sunny came to them and said, "My abusive ex-husband is on the game, these are the behaviors he's already exhibiting, I'm asking for a DNC, and making sure you guys know it," that's different. Because it gives them something to work with. And they'll take action.
I mean, @mietze is right: if someone's abusive on Discord, they'll be abusive on the game, too. But you can block someone on Discord. And then they'll HAVE to be abusive on the game, there's no other outlet and then they get their shitty asses booted but good.
But being proactive about booting someone for being a reported piece of shit can backfire hugely, if you find out the person doing the reporting is actually a manipulative jerk. I've seen both scenarios, where the person reporting is the jerk and the person being reported is the jerk. (I've lived through too many games with VASpider on.) Having a plan to offer and something to back your words up is not an unreasonable wish.
(Editing to add, no, @Sunny, I promise, I'm not accusing you of anything. It was an example, that's all.)
