I've developed systems for ISPs to handle inbound complaints from AOL & 
such, and that's exactly what we did: multiple complaints were acted upon, 
single complaints only fed into the aggregate stats.  On the INBOUND side. 
We didn't ask AOL to do that work for us.

Many recipients of complaint feedback actually /want/ to receive every 
complaint, because -- like John Levine -- they treat those complaints as 
unsubscribe requests.

Yours is not the common use case.
