Alright, since you're going with this, can you instead sign any quoted addresses from your BiPolarBob account?
Take your pick between
this one,
this one or
this one. You can sign any message so long as it is dated with the current date.
Or, have you forgotten the password to your wallet too?

Nonono, he's got a way better excuse for that, he simply never reuses addresses.
Maybe he will tell you he deletes the private keys once he used an address
(Would quote you the post from BiPolarBob4, but it seems that account got nuked
)
