Slowing down spammers via DNS

Security expert Paul Vixie has come up with an interesting technique for reducing spam and cyber crime. According to Vixie domains registered by cyber criminals can often be identified within 5 minutes by checking the WHOIS information and comparing the registrar against databases of known spammers. With this in mind Vixie proposes putting new domains in a ‘penalty box’ such that they are registered and exist for a few minutes before they can be used. This would give time for security organizations to scan the domain and determine the likelihood of it’s being safe. To take the concept even further the domain could be kept on a watch list for an hour or so and if it exhibits suspicious activity the registrar could be notified and the site could be taken down within a short amount of time.
