Ironic, yes, and it shows how dependent Bayes methods are on priors. Pick bad priors (and that can even involve assigning equal probability to all unknowns) and with a bit of bad luck you can end up in a self-confirming loop. But usually it works.
My Bayesian spam detector (actually Microsoft's which is really stupid in the information it uses, and keeps blocking people on the Peirce list).

I know how to spell Bayes but my autospellbot, which is very likely a Bayesbot, thinks that a very unlikely sequence of letters. Ironic, no?
