You may have an evil twin with the same name somewhere out there. IIRC in the recent past, there were people selling status that were essentially requesting status matches for their customers somehow, although there were some apparent hotel inside jobs involved as well as someone who was creating corporate email addresses with companies that were eligible to have their employees receive comped status or particularly good status matches/challenges.

BTW, you might want to remind DL that with your level of flying, it would be pointless to try to match/challenge for status on more than one alternative airline. You don't fly enough to maintain status on AA, UA and AS, and it wouldn't be very sensible to try.
