Spam & Serious Cybercrime hosting. Far too many problems on Corbina in past months. No action on abuse reports sent to Corbina. The lack of any action by Corbina to stop abuse of their network means that Corbina is being seen in the underground spam world as a haven for cybercrime and spam hosting, which simply attracts more spammers and cybercriminals to Corbina creating even more problems. Our users do not wish traffic from networks this dirty.
