[SURBL-Discuss] RFC: Storm URI IPs to XS list?

Unfortunately, I don't see this as very useful.  As a person directly 
affected by the issue, I would very much like to see something done to stop 
it.  However, the chances of hitting proxies and DHCP pools for ISPs just 
seems too high.

If I used such a list, I would probably want to expire entries in something 
like 90 minutes.  I use IP-based blocking with similar rules and it's quite 
effective with very minimal FPs.   If we could add entries quickly and 
people could use the list to temporarily block traffic until expired, I 
think it would be very useful (and out of SURBL's mission).

However, then comes the point of a reverse attack where they start putting 
an IP address of an innocent 3rd party.  Then we start assisting them.

Anyway, I stand ready to help.  I just don't see this as a good idea, sorry.
