How do you hide your e-mail address in the members section?

I used to have a relatively junk free e-mail account but since I
posted my e-mail address on this site I get 200+ junk e-mails a day,
even with filters!

I checked the member section and almost everyone's address is
truncated, except mine. What option do you chose to get this
trunctation?

It may be too late, but maybe I can stop my junk mail from growing
to 400 a day:(

Can anybody help?
