You might as well, since your address is stored with your key on the 
public key servers[1]. I started getting plenty of UCE on addresses 
that I had hardly ever used when I published my key.

So the spammers are actually using the key servers to harvest addresses. 
When they start using the key server data to encrypt the messages, 
content-based spam filters will be in trouble. Fortunately, 
personalising bulk mail like that is probably too computationally 
expensive to be viable today.

I find the best way to keep on top of UCE is to use a filter like Spam 
Assassin (although at times I've wished for a separate machine just to 
run this resource hog) and make disciplined use of a service like 
Spamcop to report spam. I may be imagining it, but it seems the problem 
goes from trickle to flood if I neglect filing reports for a couple of 
weeks.
