First, I assume I'm being watched at all times, particularly considering this is internationally wired e-mail through a public email hosting service with less privacy protection than a glass-walled dressing room facing a public street. And a flashing red neon sign. Less than that. The spy agencies already have it and know this stuff exists, so I disadvantage nobody by sharing it with them.
Second, I know the U.S. government has it out for me. If I throw this garbage in the trash and do nothing, it will arouse a lot more suspicion than if I report it like a good little internet user.
I'm not above opposing the U.S. government's other agencies if the cause is just, but in this instance, fighting to protect the colossally stupid (so colossally stupid it makes the whole thing feel like a set-up) is pretty low on my list.
