That's solves the problem. Maybe a opt-in visibility filter for posts only with OrangeChecks. I know this will close out a lot of people, but personally I will work on convincing a lot of them to use OrangeCheck too!

There can be many interesting solutions. To prevent closing out people we could have OrangeChecks vouching for others, to onboard trusted friends. With referral codes to give OrangeChecks for free during “sign up”. You’d tell your friend, please don’t spam or I lose my security deposit and/or ruin my reputation.
That's a good idea! In this case you can test your friendship too.
