Reporting Violations and Enforcement

  3. Immediately revoke the offender’s posting privileges to one or all ARIN mailing list(s); and/or
  4. Revoke posting privileges for a specified time period or permanently.


ARIN’s decision pursuant to this policy will be made by the President, with the advice of ARIN’s counsel, and a three member standing AUP committee [see Charter]. The committee comprises of one member appointed by the Board of Trustees, one member appointed from the Advisory Council, and one member selected by the President from a volunteer pool of members in good standing. Committee members serve a one-year term beginning in February of each year and may be reappointed.

Whenever possible, the President will ask the AUP committee to review the proposed course of action to ensure the decision is sound and consistent with the described procedures. The President has authority to issue private (off mailing list) warnings to alleged offenders of perceived violations and specific posts. In such a circumstance, the committee will be notified, in advance with sufficient time to review and provide comment to the President, of the action. Revocation of mailing list privileges will require AUP committee approval. In cases where an alleged offender wishes to submit additional information, or to seek reconsideration of a decision, this committee will also be asked to review such materials and report its findings to the President.

Community members may report to ARIN what they believe to be a violation of this AUP by notifying Information provided must include the mailing list name, date of post, time of post, name of poster and subject header, and a reference to the reason why it is believed to violate this AUP.
