By you? Not at all.
I happen to know the people at Spamhaus who compiled these lists, and the
arithmetic is quite straightforward. They watch all the domains that go
by in some very large mail feeds, count them all, and compute what
percentage were in spam. Their numbers may not be accurate to the last
decimal place, but as a general indicator of which TLDs are failing to
deal with abusive registrants, they're plenty accurate.
