Bottlenecking

Also known as Mail Bombing, and similar in nature to Spamming and Flaming, Bottlenecking involves material being sent electronically to a organisation's access points (typically E-mail servers) in such large quantities that the system becomes blocked, and genuine business material cannot get through - for example sending ten full copies of the complete Encyclopaedia Britannica to all known E-mail addresses at an organisation will choke quite a few LAN servers for a good while. Although the material itself may not be inflammatory or abusive the senders usually have a grudge of some kind, real or imagined, against the organisation, and the end result is a organisation which cannot communicate with the outside world for an unknown period of time.
