-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
I will send 0.5 BTC (currently worth ~50 USD) to a bitcoin address of the
winner's choice. If a tie occurs, the 0.5 BTC will be split evenly. If there
are disputes (including but not limited to issues about cheating and
identifying the winner), I will let AlexMennen dictate the appropriate
distribution for the 0.5 BTC.

-----END PGP SIGNATURE-----

(Note: Add a blank line after each of the "Hash:" and "Version:" lines before verifying the signature. LW's markdown seems to be hungry and is eating blank lines in code blocks.)

Someone pretending to be you could copy this whole message, PGP signature and all, as a reply to a completely different competition, and unless you can later find this message and prove that you haven't edited it, it'll look like you're offering a prize to that competition as well.

That's a good point that I hadn't considered. Thanks! I'll keep in mind that I need to be more specific in the message.

Thinking about it, a spurious copy of my message can't be used with future competitions because the PGP signature includes a timestamp (and it is publicly implausible that I would have my system time set incorrectly to the past). But it can be used maliciously with competitions that already exist at the time the signature was created.

But it'll only be believable if AlexMennen is involved with that contest as well.

If you happen to AlexMennen, it's the perfect crime!
