@ScottMGS For example, if Facebook supported this, you would be able to link to your Facebook account on your Mastodon profile and your Masto account on your Facebook profile, and they could both turn green. You wouldn't need a website yourself, you could verify your account based on an account on another platform.But because the big tech companies refuse to use the standard, this isn't possible.(All they would have to do is include the phrase rel=me in their platform's social links.)
