So an idea that has been floating around for some time is that you can verify that a link a person puts in their profile belongs to them, by checking if the linked site links back to the profile (with a special attribute that signifies intention), and that it can be used to, indirectly, verify that a profile is "real"
@Gargron this sounds a lot like keybase's proof system. It might be worth looking into seeing if there's a way to do generate and log arbitrary proofs through it. It has the advantage of the robustness of public key/private key signing but abstracts the creation and management of keys away so the average user would be able to use.
