I think that's a bit intense. To the best of my knowlege there are constant backups of SR, and one could easily pull the most recent and upload to a new .onion.Also buyers and sellers both can verify their identies with their PGP keys. You are the only one who has the private key so someone could send you me a PGP message, for instance, to see if I actually AM Anarcho47 and I could respond with proof.Keep your PGP contacts backed up, they are one of the keys to being able to transfer your rep over in case of a serious emergency. You can also use your PGP key to verify your identity on alternate selling sites (as a seller, that is).
