That seems even less reasonable to me. You're saying that you use snopes regularly, presumably because of their dedication to accurate reporting, and are frustrated that you can't correct on "something as trivial as 'shaking a soda can'" because the only thing you were able to provide them was anecdata?

It sounds like the reasons why you happily send "you're wrong because snopes" links are the reasons why you're unable to correct them and to me this sounds like the system is working correctly.
