I used to do that. But I've ultimately decided that the prospect of fighting accusations of abuse or crimes committed through my network wasn't that enticing. Proponents will try to downplay the risks by using vague ideological nonsense like "don't worry, an IP doesn't legally represent a person ;)" which, even if true, won't prevent a rather unpleasant ordeal.

Running a relay is likely fairly low-risk and still a good thing for the network, though.
