> alt.fan.warlord is a Usenet newsgroup dedicated to the dissection and flaming of signature files (sigs) used in other Usenet groups. The newsgroup was best-known during the early and mid-1990s, and can no longer be considered active. In its time, it was a notable "underground" Internet phenomenon.

> For the most part, alt.fan.warlord targeted sigs that violated a principle of Usenet netiquette known as the McQuary limit — i.e., the rule that a sig should be less than 80 columns wide (preferably 72 or less), and no longer than four lines. This limit kept Usenet messages reasonably short, conserving bandwidth, and ensured that an 80-column terminal — the most common display type — could display the sig properly without text wrapping to the following lines. The McQuary limit, sometimes referred to as the "McQ limit" and often misspelled "McQuarry," was named after George F. McQuary, a frequent contributor to alt.fan.warlord.
