How is the Piracy community adapting to port forwarding becoming a rarer premium feature, and most users on public trackers do not have it? Is the bitorrent protocol in need of update? (lemmy.blahaj.zone)

It's not v6 itself, it's rather lack of layers of nat that prevent forwarding a v4 for most folks.

Hmm, so no firewall in the router blocking ports, instead blocking happens on the actual client?

Port forwarding is necessary due to NAT not firewalls.

It's not that your router blocks new incoming connections at port X, it's that it does not know which local client it's meant for, since it's addressed to the public IP that is held by your router.

With IP6 it's lan client also gets assigned a public IP6 address (as there are plenty) and so the router receives a connection addressed to a Lan client and knows where to route it.
