It's very useful, but not always cheap and can be open to obvious
misinterpretation - it's cheap until someone attempts a dictionary attack
or similar against you from, say, aol.com addresses, you hit AOL with an
equivalent attack of callouts which looks like the same sort of wrong-doing
and your calling-out address (or more) gets blocked.
