yes I understand and recall your explanation. I am interested in two things:
1) the possibility that Spamcop has a bug in the way that it assigns "ISP
not interested in reports" to the domain name rather than the IP address,
and 2) the question of whether this kind of round robin can be halted by
informing the domain name server, as suggested by Redstone.

Sounds like (1) is correct; it is a bug in Spamcop.
