Sure you can. Read up on anonymous and pseudonymous mail systems. But
that's not the danger what Shaun was talking about. The "Web of Trust"

paralleled by the process of signing email.

(The dangers of key signing have been discussed extensively on the
cypherpunks list. I suggest reading the archives.)
