Well, there is precedence for this. Long lost twins, separated at birth...
We could "pass the hat" (raise some money), hire one or two professional "profilers" to review the "posts", come up with "profiles" for both; then compare notes.
Or... Arrange DNA testing through a "trusted" third party... (Nah, that would require the cooperation of both (or the same?) parties - or a lot of stealth.)
Who knows where the trail would lead...
(Meanwhile I'll be strengthening my "privacy" safeguards and/or increasing my monthly "protection" payments to ******.)
Happy Birthday Carbon(s)!
P.S. There may be an entire "clan" of Carbons out there:
Carbon Monoxide,
Carbon Dioxide,
Carbon Trioxide,
Carbon Suboxide, etc...
