General PSA: in most situations these things like "terms of service" and "breach notice" have no legal effect. (I am not a lawyer and this is not legal advice)
What they do is the same as a "cease and desist": they warn you that Discord might consider suing you or might try to ban you by technical means.
It's all about business, not what the terms say. If Discord thinks BotGhost is good for Discord's bottom line, they'll let it exist. If they think it's bad, they'll stop letting it exist. I haven't the slightest clue why Discord now thinks BotGhost is bad for Discord's bottom line, but it's probably got something to do with legibility (in the Seeing Like A State sense) to investors for their IPO. Or they're working on a competitor internally.
