what's discord tos have to do with diamondfire exactly? please take it up with discord support
I mean the DiamondFire server rules don't seem to have anything about sending "private info" of someone, the closest I could find is
Harassment and other harmful behavior toward the DiamondFire community can result in removal, even if the behavior occurs off-platform.
but that seems too general to even think about what it includes. Doxxing is wrong, yes, but there aren't any rules about it on the server.
There is a rule on the forums rules about doxxing but that only gets your forums account disabled.
so that's it, if they ban someone for sending some guy's old general location from an ip that was previously sent in chat by another guy (which isn't illegal btw), then they could also take action on someone for breaking the discord TOS (ofc no one wants to try to get reasonless banned, I am just bringing out a possible point).
