You might think you're not the same, but you do the same things that get you banned.
You leeched for some rounds, by just camping spawn and kicking/nudging people AFK, who, when they came back, helped the team a lot more than you did for most of the time. And then I see you shooting a teammate with a crossbow twice (with no enemies around), the second shot killing him. The length of the ban comes from your ban history.
I'm really tired of seeing people leech in DTV, just screwing around with other leechers far away from the fight even for entire rounds, while the rest of the players are killing and finishing the rounds for you. It's unfair for them, and, if your definition of fun means breaking the rules, you should change that or quit playing.
The thing is, most of the times, it's the same people that get banned, and, precisely, because they keep doing the same all the time, and not because they don't know the rules.
