..when someone just spawned and gets their eq, opens the door and gets killed in a instant, i'm highly sure that's a spawnkill.
There's over 4 ways out of the base. There is no way 1, or even 2 for that matter, can cover that many doors to where you don't have a chance to pull out a gun and start firing.
Also, if that^ is what you think a spawnkill is, you are misinformed.
A spawnkill is when a player spawns, automatically gets damaged or killed, and has no chance to damage/kill the player(s) shooting at him/her. These players had time to spawn, grab the weapons they wanted, realize that there are 1 or 2 enemies outside of their base, choose an exit they want to take, take that exit, and find the enemies.
Notice in the pictures that not one player complained about spawnkilling until Cavik and I reached a 10+ killstreak. They were simply getting angry at not being able to kill us and began accusing us of spawnkilling or spawncamping.
