It requires the people contributing the work to have the integrity to actually follow the project’s rules. It’s not OK to violate the project’s rules just because you don’t think you’ll be found out as a filthy fucking liar.
I mean best of luck policing this is all I'm going to say. We will soon be back to the "core contributors only" kind of policy in many projects I imagine to avoid the slop spam. The verification will be at the conferences.
