I thought there was a vetting process.

They claim there is one... I am finding it hard to believe anything is actually being checked, though.

A previous offender had actually registered dozens of his sockpuppets with numbered emails under a private domain (as in 1@, 2@, 3@myprivatehomepage.xyz) and free temporary phone numbers. So yeah, so much about "vetting", I am pretty sure there is nothing other than a simple check for dupes.
