The servers in the range 222.127.1.18 ~ 222.127.1.27 have been discussed in this forum for at least the last 2.5 years.

As of today they are still in the public pool, still being offered to pool clients and still failing to respond to a large number of requests from the Philippines and wider Asia/global region.
So the question I have is what happens now? How do these servers get removed/blacklisted from the pool? Who makes that decision to remove them? What information do they need so they can make a decision to keep and/or remove these addresses?
