> .com and .net domains made up approximately half of all domains registered...they accounted for just over 40 percent of all cybercrime domains.
Hardly earth shattering. .net and .com are still pulling 80% of their weight when it comes to cybercrime. And the article concludes that the main reason the new TLDs are disproportionately used is because you can sometimes buy them cheap in bulk.
Maybe the real story here is that the ccTLD registrars, who weren't mentioned, are disproportionately good at deterring cybercrime.
