Valve Bans 40,000 Accounts

During the Steam Summer sale, Valve's Anti-Cheat system (VAC) banned a record breaking 40,000 accounts. Typically 3,000 to 4,000 accounts are banned each day with the previous record at 15,000. The hypothesis for the large amount of accounts this time around is attributed to cheat makers using dummy accounts to test out what software can get past the VAC.
