A community vote for NSO legality has started on the Discord. We welcome votes from all community members - runners and viewers alike. To vote, join the discord via the link above and check the #announcements channel for the voting form.
I'm a little late here, but that provision exists because in other communities there have been people who have come out of no where and claimed first without any prior runs on the board. Proving an emulated run was cheated in any way is actually quite difficult, but it is far less likely someone has cheated if they have a bunch of runs that show steady progression. That proof can either come in the form of streaming runs, submitting runs as their time improves, or showing proof of recordings if they do end up claiming 1st out of no where.
