alt Hacker NewsWith 5400+ people I am betting that you have at least one person in your 'web of trust' that no longer deserves that trust.
That's one of the intrinsic problems with webs of trust (and with democracy...), you extend your trust but it does not automatically revoke when the person can no longer be trusted.
Of course! There are always edge cases, but I would suspect the number of bots signed by reputable keys to be near 0%, and the honest human score in this trust graph to be well over 90%.
Compare to how much we should trust any random unsigned key signing commits, or unsigned commits, in which the trust should be 0% unless you have reviewed the code yourself.
