If your flash content and/or website scripts become too resource intensive, we will typically contact you first to give you a chance to remedy the situation. If you don't respond to the support ticket then we will typically just disable the offending content or website until the issue is resolved. You would have to be fairly blatant about abusing our hardware and/or bandwidth before your account is terminated.
If you need assistance with problematic content or scripts, you can also fill out a support ticket and someone from the technical support team can assist you with this.
