I am a merciless spawn camper and it is not cheating. Blame the developers for making spawn camping possible, not the players who take advantage of it.
For those who hate spawn camping, here's the question I always pose: how long after you spawn do you expect me to wait to kill you? Should I wait until you get a power weapon or until you pick up some sort of power up? Should I wait until you have me at a disadvantage before firing?
No game allows you to spawn camp the second the match starts. Spawn camping requires one team to lose ground and the camping team to move into their territory. If you let me move into position to spawn camp, then there's some sequence of events that preceded that which gave me the opening to spawn camp. And let me tell you, if I have the ability to neutralize your threat immediately and kill you the second you spawn, I'm going to do it.
Games reward you for winning. No game gives you awards for playing nicely or politely. I want to win, and I will do whatever it takes to win, with the exception of manipulating the game by outside means (standby, modding, glitching, etc.). And if I screw up and put you in a position where you can spawn camp me, it's my own damn fault.
And to take this a step further, there is no such thing as "cheap." "Cheap" is a word scrubs use to define an arbitrary set of rules they have created that no one else adheres to. This applies to throwing and repeated tripping in fighting games, camping in shooters, etc.. People cry, "cheap," when they mean, "I have no idea how to defend against what you're doing so I'm going to try and insult you."
