I'm pretty sure the "algorithm" is "we count the number of end-user flags/reports, and if > X we remove it"?

Public knowledge of what "X" is doesn't really help, I think, other than to aid spammers? And a requirement to "talk to a human" upon hitting X would surely immediately degrade into "Google has reviewed your appeal and has determined that the infinite block of your account remains in effect. There is no further appeal"?
