Very interesting note!
This seems a bit similar to PGPs verification levels for signing other people's keys.
There are four signature levels:
Level 0 signature: no indication. This is the default level and is usually used by people who don't know or don't care about signature levels. A lot of people don't specify the signature level when they sign public keys, so there is no reason to discard these right away.
Level 1 signature: personal belief but no verification. As the name says this level is used when someone signs a key but was unable to verify the identity. Used for nicknames, most of the time, as you can't really prove the identity behind a pseudonym. Be careful when you encounter a level 1 signature on a key with a full name and e-mail address. These levels have to be specified manually, if someone changes it to level 1, it might be for a reason.
Level 2 signature: casual verification: These signatures usually mean that people have met and checked identification, but didn't know eachother upfront.
Level 3 signature: extensive verification: The level used when the signer was absolutely sure that the listed name is correct. Usually this means that they have known eachother in person for years and have checked government issues identification.
