Valve Cracks Down on Dota 2 Players Exploiting Compendium Bug

Valve has taken action against Dota 2 players who took advantage of a bug to boost their Compendium levels for free. Those found guilty have had their ill-gotten rewards and items revoked.

Valve:

In a recent discovery, it was revealed that some players were manipulating this bug to acquire more Compendium levels than they legitimately earned. If you were one of these individuals, your account has been purged of items acquired through this exploit, and your rewards have been reset to their default status. You can claim the correct rewards by visiting the Compendium's designated page.

Certain players have reported receiving bans for exploiting the Compendium. It appears that account suspensions were issued only to those users who attempted to profit by selling capsules obtained unfairly.

The Compendium bug was identified on September 28th. To exploit it, players needed a fresh pass with unused levels and an auto-clicker that repeatedly clicked the mouse. By having the program repeatedly activate the "Apply Levels" button, account owners could accumulate numerous levels without any associated cost.
