Use the former for console nonsense, item-dupes, UUDDLRLRBA, etc., but having a separate tag for questions like How does Valve Anti-Cheat work or How do I determine if someone is cheating in Call of Duty:Black Ops strikes me as sensible. They are two very different categories of question.
This tag is for cheats conducted through exploitation or modification of game files or the use of external programs to provide an unfair gameplay advantage in competitive multiplayer games, and the various means used to counter them. Maphacks, Aimbots, Lag Switching, etc. For questions regarding other uses of the term, see cheat-codes.
