I loathe these guys/gals. I get their mails **and** emails, but the worst part of the experience is my clients who are not very net-savvy go "chicken little" on me as a result of receipt, sometimes even to the point of anger. "I thought you were taking care of this for me, isn't that what I pay you for?" (No. :-) ) It's cost me untold hours in "counseling."
Not a lawyer, but even so . . . this should be illegal. <ducks>
