Look at their partners: Facebook, Microsoft, Google, YouTube, Twitch, Discord, Twitter, Reddit. This is how they all derive their terms of service. I noticed any time Discord had new rules or policies usually reddit followed suit.
I also noticed Discord has a new TOS update recently that put a lot of their known policy into black and white, but included an interesting tidbit about being able to ban people for off-platform TOS violations. I forget the name of a Twitch streamer who got banned recently for off platform behavior but if you are still following you will note how a policy in one becomes law in another and vice versa. They are all in some alliance and Elon Musk would likely ruin this.
This is extremely uncommon knowledge that you only run into it if you moderate on Discord and Reddit and dig deep enough. But also it should frighten you that if you do anything wrong all these platforms will ban you in unison and they absolutely can based on their TOS.
