Spamhaus has slammed Yahoo for allowing the registration and/or hosting of thousands of domain names that can be used in phishing attacks. These domains have words in them like “bank”, “ebay”, and “PayPal”. Obviously, not all of these are used for phishing attacks…some might be reviews or services related to eBay, PayPal, and various banks. I’d be curious to see the breakdown between “bank” and the other keywords, since there are plenty of legitimate uses for domains with the word “bank”. But this raises a valid question — should domain registrars get into the business of censoring which domains they allow clients to register?
