I have hesitated to kick for it until it was made officially spawncamping. However, if people are not spawning at that spawnpoint regularly (of course there are times when the fucked up spawn system we know and love will spawn people right in front of you, and spawncamp spots make that worse) then there is no reason to kick. Even if once or twice someone spawns there an gets spawn killed, I wouldn't kick for it, and I see absolutely no reason to. If you ick for that, then you oughta kick for the people who have spawnkilling down to a science and just run 'em back and forth.
So, yea I'll kick for it when it's spawncamping. Please be reasonable about who you kick there.
