Same is doing spamhaus for emails. But slowly almost all email servers "subscribed" to spamhaus to "verify" an email or a server and now spamhaus can lock down an entire communication with a specific email server.

Is a dangerous slippery slope if we really want to have a permissionless network. They start with destinations, and later will be imposed also on senders... The BTCpay service will say, ok I want to see if you are also "verified" by branta...and so on.
