It does look promising that spammers are concentrated in so few bad neighborhoods but I suppose if one neighborhood gets burned, it will quickly be replaced by a new one. We could play hide-and-seek for years and this won’t erase spam for sure.

I agree with Lisa that there’s some encouraging news in learning about most spammers targeting only a specific number of bad neighborhoods. This, however, does not in any way tell us that we should take spammers for granted. It only helps us determine how we should attack spam since we’ll know from where it originated.
We should come up with programs targeted specifically on fighting spam of phishing. In the end, everything depends on how much we know about bad neighborhoods and spam in general. While there is no surefire way of eliminating spam, there are countermeasures we can use.
