Now that the subject of proof being required for consoles and emulators is brought up, I'd like to say that if TSC goes in that direction video proof should be required for the emulators as picture proof can't distinguish enough information, and picture proof at least should be required for consoles, if proof were required for each submission. There should be a system in place that lets you choose which platform you used. As said before, people can say they played on the wrong system, but no security system or rules system is perfect. The goal is to limit the damage as much as possible.
I'd also agree that a certain place on the chart should be required for proof if that type of system was implemented, as people said, all people should be free to use this site without too many restrictions, and the less competitive player may not want to prove every stat, but that could also lead to problems too. I agree that a proof system should be implemented as soon as possible, regardless of what type of rules are established.
Keep in mind that requiring proof for every stat or every stat at a certain level will weed out cheaters and turn off honest players alike, whether it be 1 person for each category, 5, or any number of people. You have to make the rules well developed but also determine what your target audience is. If you make a system where people can choose what stats they think are false and ask for proof, then you ask for the appropriate proof, which could be an alternative to requiring proof for every submission. The goal of the site should lean toward making competition as fun as possible, making it as easy as possible for players to compete/upholding the rules, and making the site a haven for the best Sonic video gamers in the world.
I personally would not like there to be proof required for all stats or even all stats at a certain level. It is too rigorous and will be harder to keep up in the long term. Twin Galaxies had a system like that (even if it was video proof only) and now it seems they are in a tough spot financially/running the company. You don't need to go all out in making new rules about proof, a well-integrated system where people can ask for a specific type of proof and choose the stats they think are false works well because they can pick stats that are most likely false, and leave the lesser ones alone. Even if those lesser stats are false, you can't win them all. Pick your battles and limit the number of false stats as much as you can. They can choose lesser stats if they want, and those stats should be investigated accordingly. A team of people should be assembled to work on that process if it were to be implemented.
The site should try to not go overboard and overthink this process. Banning emulators is not good because they are a popular platform, and TSC has made the decision to allow them in the past, so they should still be supported. The people that will leave because of new rules for emulators would leave even faster if emulators were banned. New rules for proof that I mentioned earlier and a new integrated system for both consoles and emulators would work well, to help the site gain some more stability, as that is what it seems the staff is after. The majority of TSC seems to want the site to change, and you have to make a change if you want the site to evolve and grow.
