What does this requirement mean?

Submitted video must contain the full run, and a permanent link behind no paywall.

I did not understand very well hehe thank you

From my understanding it just means the link to your video/PB run should be permanent. So no links that expire after some time. Let's say if you dont highlight your session/run on twitch (which is permanent) the stream itself gets removed after 14 days. So if you would submit that and it expires after those 14 days that wouldnt work for submission. And for paywall: the link should take the mod to check your submission directly to your run, not to a bad site where they would have to register/pay first to see the content. :) Did that help clarify?

Thank you, your contribution was very helpful :)

you're welcome! GLHF!
