That the slope becomes slippery does not in and of itself mean we cannot look at what was asked and frown. Raziel lays out a scenario that looks suspiciously like address harvesting a la spammers. So far, Raziel has not offered any further explanation of his/her intentions that might clarify this point.

In my mind, this question skates right at the edge. Given that useful conversation has occurred, I'm personally inclined toward leavgin this post stand.

The worst thing about including the "extracting emiail addresses" function is that it obscured the actual issue. Other posters have spoken to the technical issue at hand.
