That's fine, except that this being a public forum means that the spammers
in here will be posting that info on their forums as we speak. My point
being that if this method became the norm, then it would not be long before
spammers wrote their software to work properly. So it will work for a while,
but won't work indefinitely. Although if the right measures and filters are
in place, 99% of spam can be blocked anyway, and for the majority of spam,
would continue to work almost permanently.

All the best
