The IP block that has been placed on the above listed IP address is a temporary block that is automatically lifted after 12 hours in an effort to prevent the spidering activity from proceeding. There is no action required of you for this block to be removed, unless ACM identifies an unusually large number of such blocks within a short period of time. In such instances, you will be contacted by ACM staff to work with you to investigate the source of the spidering or robotic activity at your institution so that it can be prevented in the future.
