Mythic has announced on the Camelot Herald that they will be using new anti-hack technology when their free RvR expansion, New Frontiers, is launched. Here's a snip from the announcement:
As part of the New Frontiers development effort, we have developed new "hacker sensing" technology. Early tests indicate that we can identify hackers better than ever before, and at the same time with fewer hours of investigation. We're very excited about this, as it will significantly speed up our banning process. We have always cared very much about getting cheaters out of the game, but the process was so time consuming that it frustrated both ourselves and our honest players. Now, our first New Frontiers bannings and suspensions will happen during the first week of launch.
