well first and formost a speed hack is obvious... the shoot faster, reload faster, and when they have their knife out they look like they are teleporting. from what i know (and i may be wrong) since everything is going through the internet what you are probably seeing isnt at all accurate. with the given lag time of their computer to the server and the server to you things like pinpoint aim and such can be off. i wouldnt accuse them of hacking right off but it does take a good eye to spot hackers. ive have plenty of experience but we all make mistakes.
