Microsoft is cracking down on players on its Xbox Live gaming service who use hacks to artificially inflate their scores.

“Today, we took action,” said Larry Hryb, Microsoft’s Xbox Live programming director, in a blog post Wednesday.

Hryb, who blogs under the pseudonym Major Nelson, said Microsoft would reset cheaters’ “gamerscore” accounts to zero and eliminate all past achievements. Their gamer profiles would also publicly show they’ve been caught cheating, according to Hryb.
