Ramifications
Some companies and leagues ban suspected cheaters by blacklisting specific installation or serial keys, or user accounts, meaning that the player is effectively prevented from playing the game online. In such cases, the banned player may be able to avoid the ban by purchasing an additional copy of the game which will include a new unbanned serial key.
While game publishers are known to ban players employing cheats, the actual number of players banned is usually not revealed. Exceptions to this include Blizzard Entertainment and Nexon, known for banning cheaters in batches, and publicising the number of banned accounts in order to discourage others from cheating.
