No. We're asking that the recipient place a value on his own time, and if the sender isn't willing to pay it, he is blocked from sending the email. That's a perfectly normal business transaction. "If you're not willing to pay some minimal amount for my time, then there is no reason for me to listen to your sales pitch or proposal."
Imagine if we had implemented this for the phone system years ago. We could have avoided all of those annoying telemarking calls (and scams) around dinner time. LOL
