Well the obvious answer seems to me to stop majordomo at toad.com accepting ANY messages from anonymous sources but let pseudonyms post, pseudonymous posting allows the owner of the nym to accumulate reputation capital without disclosing his or her true identity.
Paul Bradley accumulated oodles of reputation capital with his obscene rants about "brute force attacks on one-time pads".
I do not see what was remotely "obscene" about a slip up of this kind, and please refrase from using the plural where it is not appropriate, I posted such a mistake once and immediately realised what I had said and retracted it.
Now he wants more censorship.
If you had cared to comment in the rest of my posting to your reply you would have seen that immediately after stating this solution I confirmed that I do not encourage this or condone it as it is censorship, but that it was merely a solution, not a good one granted but still worthy of mentioning. For those who (ahem) overlooked that part of my posting here it is again.
Bear in mind of course that this is a purely technical answer and I happen not to believe that anonymous posting should be stopped.
But of course you chose not to comment this in as it allowed you to credibly rant about me wanting censorship, at least argue with someone you have a dispute with rather than just randomly picking people and quoting parts of their posts out of context then flaming them.
