@erichfi for this bug we are only searching the github API three years in the past from the current date to avoid github's rate limit. A large amount of this user's contribution history is from 2019 making so it so that we do not find his older contributions and do not issue them a stamp. I put together this #1715 which would search 5 years back.

The github rate limit is 5000 points per her and each of our requests burn 1 point. So this would bring the number of possible github verifications per user down from a maximum of 1666 to 1000. 1000 still seems like a reasonable amount of github verifications per hour, but don't want to fix one problem to cause another. We could also add messaging that explains that we are only able to search through the user's x amount of years github data due to rate limiting. Thanks!
