> Evan Boehs observes that Jigar Kumar and Dennis Ens both had nameNNN@mailhost email addresses

This is the second time I've read this "observation", but this observation is just wrong? Jigar's email is "${name}${number}@${host}", yes, but Dennis's is just "${name}@${host}" — there's not a suffixed number. (There's a 3, but it's just a "leetcode" substitution for the E, i.e., it's semantically a letter.)

(They could still both be sockpuppets, of course. This doesn't prove or disprove anything. But … let's check our facts?)
