"Warcraft III Map Hack Users Banned - 9/06/2002
In keeping with our aggressive stance against hacks and cheats, we have closed 20,504 accounts that were found to be using Warcraft III map hacks, and removed their ladder records. In addition, the CD keys of those offenders have been banned from ladder play for two weeks. We will continue to monitor the Warcraft III realms for malicious players. Please note: repeat offenders can suffer permanent removal from Battle.net if they continue to use hacks.
We regret having to employ these extreme measures; however, certain unscrupulous players have impaired the game play of the Warcraft III community as a whole, and severe action continues to be warranted and required.
We appreciate your understanding and cooperation in this matter. If you would like to report additional instances of hacking or cheating, please contact us at
hacks@blizzard.com. Thank you again for your continued support.
