We only accept abuse complaints in writing. Please include detailed logs or full email headers with all abuse reports. We are unable to respond to every report we receive, but all submissions will be reviewed by a technician and appropriate action will be taken if it is warranted. For legal reasons and for proper record-keeping, we cannot accept abuse complaints over the phone.
