The community is already enforcing verification in #introduceyourself

Somewhat. Mostly it filters out the weakest/cheapest frauds. And the vast majority of the users haven't ever done that (I think at this point the majority doesn't even post introductions at all, and many introductions are lost in the noise). Verification, in general, is an onboarding killer. Even for #intoduceyourself posts earning thousands of dollars there have been debates whether being "too strict" on verification is being too hostile to new users.
