If his account was breached it would most likely be from the malicious use of his token. If so, someone had gotten access to his Discord login token and used it to send messages on his behalf without any need of logging into his account. This completely bypasses 2FA and Discord will most likely not send him an email as they won't even know.

Evie was banned for talking about a video which I cleared with staff in retired chat to be SFW. I also played said video in theater which we all watched and enjoyed so can staff make a SINGLE decision if things like this is SFW or na.
Keep in mind, i also posted the same video in discord gen chat. If it is NSFW, boot me the same as Evie
