I guess I don't understand ... what is it about this change that will make it more likely that spammers will use .com / .net?
Most spammers use .biz domains because DNS updates for .biz are almost-instant. It mean that if a web host pulls the plug on a spammer's site, he can change the name servers and point his domain to another web host in around 5 minutes. So spammers use this as an insurance against action by web hosts. They keep multiple backup sites ready in case they need to change DNS. Please remember that DNS for .com & .net propagate in 12-24 hours for most domains.
Will rapid DNS updates impact SPAM?
Verisign anticipates negligible increases in SPAM as a result of more frequent updates to the .com/.net zone files. Rapid updates to .com/.net are consistent with processes in place at other large domain registries today.
