This has been done before (nos' private key got leaked), and it turned into a web-of-trust proof abuse machine, I wouldn't recommend it
Burn you private key should be implement on here ! Have no idea what the concept but even if I will really delete my private key and someone already has an access to this account it will end up as I described above ! Why then I wouldn’t just give up my private key at the first place so retards will take it over and you all will know that this account is done ?
