By necessity, so that Reddit wouldn't have been obliged to intervene and close the community.

I considered the r/Piracy sub a 'gateway' - it didn't overtly provide pirated content, but it made the pirated content safer and more accessible for people who weren't already familiar with it, or updated us on news for platforms going down or changing hosts. It made piracy accessible.

Of course accessibility means bringing in low-effort users, lurkers, and those who make choices out of comfort/convenience over principle, but it still provided a service.
