Eventually, there's going to be monotone spam.

In a distributed network of monotone installations, especially in a large one, 
someone, somewhere, is going to check in a revision containing load of 
spam, and netsync will quickly, and efficiently, spread this to all the 
machines in the net.  Once it's done once, of course, it will be done 
again and again.  Now the security model can be configured to 
ignore the certificates relating to the spam, and maybe repeatedly 
reconfigired as necessary,  but do we have any effective way of 
reclaiming its disk space?

Now I don't think it's urgent to solve this problem now, but it's 
important to brainstorm solutions, so that when the time comes, we won't 
have implemented a lot of things that make spamfighting hard.

This is related to the problem discussed a few months ago about a 
mechanism to permanently expunge a particular revision from all copies 
that might exist enywhere.  There I believe the motivation was to revoke 
copyright violations.
