I think this might compound the danger of -u.  Scenario:

You bind a "bogofilter got it wrong" key to your mailer to pipe the
message through bogofilter -U.

You get 5 similar spams that bogofilter says are not spam.  You pipe
the first three through and bogofilter now starts calling it SPAM.
The second two your pipe through -U cause bogofilter to doubly count
it as non-SPAM.
