I'm guessing they have had to deal with DDoS attacks a lot, and as a sysadmin I can sympathise with their frustrations - it doesn't just affect the person fleeing to them, it affects their entire hosting platform, their other customers, and ultimately them getting paid for hosting those other customers. They're probably sick of it, which explains the drastic action. I can understand why they would threaten this if they've had to ride through multiple attacks, especially if it appears someone under fire is using them for 'cheap DDoS mitigation' when it's specifically a service they don't offer.
