No, what I'm asking for is that anyone that is participating the pool
initiative should be required to accept connections from any
reasonable client, and specifically not be allowed to filter out
traffic from a large ISP just because they acted as asses 20 years ago.

Having an "exclude" option is a band-aid solution to this problem.
