You will see frequent cries of hacks (in my own personal experience, in 3 of 10 rounds). Inexperienced players will fail to distinguish between a lucky kill to a kill afforded by a hack. Also because of the cheating, this created a growing culture of distrust among a number of legit players. Hack players are either hungry for attention/recogintion/praise of their 'skills' or they are just doing this to provide grief to other players who play fairly. While I don't immediately cry 'hack' when I smell something fishy in Black Ops server until I review the recent clips, I've caught quite a few definite indications of hacks, and one of them had no shame to even declare 'Good Game' after each round. I hope they will be helpless in real life. Players who run hacks to make things easy for them shows their outlook on life.
