This is going a bit off topic, but I'll respond anyway. This post, of course, applies to first-person shooters:
[*]If you spot someone that is constantly jerking while shooting and running, THEY ARE using an aimbot
Jerking alone doesn't mean anything—when I play, I constantly jerk in all directions, checking my six and my flanks, looking up and down, scanning for hostiles and keeping track of my teammates. However, if a player is consistently jerking straight to targets and getting kills as he does so, it's a good bet he's cheating.
If you ABSOLUTELY know that your killer could NOT have known where you were, but still kills you everytime, they ARE using chams/wallhacks/ESP hacks
Not necessarily. Experienced players learn the common spawns, routes taken, and positions camped by other players. They can also use the process of elimination to determine where a target is in the map by observing where said target
isn't. You may, through inaction or unconscious action, reveal your location to an experienced opponent.
If you killer comes around a corner, or enters a room, and IS ALREADY shooting his gun in your general direction, that means he is using a cham/wallhack/esp hack
This does not constitute proof of cheating. Firstly it fails to account for sound, which is exceptionally useful in locating players behind solid objects, given a good audio setup and competent player. Secondly, the opponent may have located you by means iterated in the preceding point. Thirdly, watch out for parts of your avatar sticking out through solid objects—this happens in many games including CoD4. Finally, keep in mind that opposing players may be communicating your position to each other—a particularly good possibility if you kill one opponent and then are killed by another on his team, before you have moved.
If someone can kill everybody on the map from their current position withing several seconds, they are either ghostmoding/telekilling/opking
Probably, but this depends on the map, number of players, and other variables.
If someone is killing you from a distance with any weapon within two to five seconds, they are using no recoil/no spread/no sway in conjunction with an aimbot
I don't understand—do you mean if someone is killing you multiple times within a short period? As in they kill you, you respawn, and they kill you immediately again?
Point is: many good players get kicked/banned from servers by those who simply don't understand the techniques they are using. A quote from a server I used to frequent: "Remember: most "hackers" are just better players than you." It's true. YouTube has many videos uploaded by skilled players, showing themselves doing amazing things without cheats. Watch a few and then ask yourself: "If I were on the opposing team, would I accuse this guy of cheating?"
You have to really put yourself in the shoes of the other player and consider the sounds he's hearing, the techniques he's using, the shadows and tracers he's seeing, etc. to avoid accusing the wrong person. Because if you end up accusing a highly skilled, cheat-free player, you're just going to make yourself look like a whiner.
