I mean blacking out forever should be what r/piracy is doing. If r/piracy reopens, then the admins are more incentivised to ban it, whereas if it remains private, we can still have the description up to redirect visitors to this lemmy, and since the subreddit is private, admins couldn't care less about it since there is no legitimate DMCA claims for a privated subreddit. They might still eventually ban it, but being private will put the act of banning r/piracy into a lower priority, so the lemmy redirect lasts longer.
