Perhaps this is my tinfoil hat speaking but......aren't you worried about the "paper" trail you are submitting to this exchange of private key for CLAM? Much like when the Coca-Cola created this huge online photo album of people's faces in order to find their "doppelgangers," not for a huge facial recognition system instead.
Yeah, it would take a lot more to get me to divulge even my defunct private keys. Though bagels and tasty coffee might work.
