So, they make a flaw in their game that makes it possible to prosper from spawn camping, and instead of fixing the problem, they ban the people that found it...I hate spawn camping, actually, I hate multiplayer shooters with respawn, I prefer the round to end and then everyone lines up again and runs the next play, kind of like football. Respawn shooters are like basketball, the play is always moving and everyones everywhere.
They could have added more spawn points or made it so that if someone was camping one then they'd spawn somewhere else. Other people have pointed out spawn protection, someone said 5 second spawn protection but even 3 seconds would be plenty of time. Perks like painkiller from MW2 prevented dying instantly after coming back (if you were on a dying streak, which these guys were). Rank boosting is nothing new in games, people with multiple consoles (I could, but I don't, for instance) can play 1 on 1 or have many set up and just kill them all with one character. This is a problem in Socom but no one really minds it, it's just some digital rank that comes with time, rather than skill.
