Re: [Asrg] Opt-out lists and legislation

tweaks that can be applied to make processing more efficient but the upshot
is that anyone can check against the list without the list being a source of
spam addresses.
<Some more stuff snipped>

While such a list would not provide email addresses, it would allow email
addresses to be validated.

If I am a spammer in Elbonia with a 1,000,000 email address CD, then I
could submit each address in turn to the Opt-Out list.

Is abc(_at_)example(_dot_)com in the Opt-Out list?  Yes
Is def(_at_)example(_dot_)com in the Opt-Out list?  No
Is ghi(_at_)example(_dot_)com in the Opt-Out list?  Yes

abc(_at_)example(_dot_)com and ghi(_at_)example(_dot_)com must be valid email 
addresses, so
I'll send them some spam.

This is why one does not respond to Opt-Out requests in spam; it
validates the email address to the spammer.  This system would allow
them to do this automatically.

I was at the IAPP conference a few weeks ago and there the FTC revealed that 
there
unsubscribe test campaign resulted in no increase in spam to those addresses at
all.

Which was amusing to here since the TRUSTe rep just before him said never do 
this
as you will get more spam
