There are verification systems out there. A business using any social media should be happy to use them, even if you have to pay for them.
Heck, even
@CatchDrop uses one so Kudos to them for attempting to KYC.
I've got an idea, there should be a way to link your business's EV SSL certificate (Extended Validation) to your social media accounts.
Extended Validation involves a full background check of the organization. The CA will make sure that the organization exists and is legally registered as a business, that they actually are present at the address they list, and so on. This validation level takes the longest and costs the most, but Extended Validation SSL certificates are more trustworthy than other types of SSL certificates
So if your domain is EV SSL certified, and you can create a valid TXT record in DNS for verifying your social media accounts, that should be good, no? It's kinda like domain ownership verification for various platforms, with the added security that your business has to also be EV SSL certified.
That seems to me like a reasonable way to be auto-validated as a legit business linked account.
But verification aside, I think it is perfectly in their rights for any social media platform to charge business customers for an account. So I think some automated validation like I mentioned, or even a one-time-fee for a thorough verification directly with the platform, plus an annual subscription, is completely justifiable for business use.
I think CIRA could/should do the same thing. Charge a one time fee for a registrant account validation. Once you get approved, then you are free to put as many domains under that registrant ID as you like. Optionally, the first time you register a domain, you still pay and agree to the CPR like normal, but you also agree to comply with a thorough registrant validation within 60 days, otherwise your domains tied to that account get released and you forfeit the funds paid for them. Everything can stay under privacy, but at least we know CIRA can claim to actually KYC.
