Well, the whole point of a DMCA notice is to let you remove content BEFORE the legal action. And I don't know if you looked at it, but the Piracy sub is only discussion, with a rule that disallows any links. If anything, they'd go for the actual instance that hosts it, not this totally unrelated one. I don't think they even know Lemmy exists. And yet, the Piracy Reddit is completely fine.
