Revy

Again, my concern isn't really the guns. That's an inconvenience that I could do without but not what I really care about. You haven't seen it, so it doesn't happen? It happens to me a lot. I can name three different people in the past 24 hours who have given away my location directly resulting in me being killed. Generally people who freekill and do the more traditional form of teamkilling are thought of as massive dicks. That's why there are rules against it. Because it's a horrible thing to do that completely ruins someone else's fun. It's not fine. These people are intentionally doing something that negatively impacts their teammates. How can you defend that behaviour?

Snitching on guns is annoying, but it isn't my main concern. It's more about snitching on your location when you sneak off, which is when you're kill on sight. When the CTs would otherwise have no idea that you're out of their grasp and going for a weapon, and your teammate snitches on you, that action that your teammate took directly results in you dying, which is, as you say, teamkilling. HOW? How is it fun for my teammate to take an action that directly results in me dying when I'm trying to do the objective? It doesn't matter if it's fun for the teamkiller. That's not how rules are made. It's "fun" to freekill, it's "fun" to teamkill, it's "fun" to do things to other people that negatively impact their experience but not yours.

My point is that "snitching" isn't counted as teamkilling, even when it directly is. If someone says I just went in a vent, and I directly die because of it, my teammate has effectively killed me, but somehow isn't responsible for it. I could have won the game for my team and instead I've been screwed over by someone who goes out of his way to do this every round. It's obnoxious, and it shouldn't happen every map, or at all.

Teamkilling might be funny to the person doing it, but it isn't funny to the person on the receiving end. It's great that you think teamkilling is funny, but there's a reason intentional teamkilling is banned on every server. This is just an extension of teamkilling suited to this specific game mode.

Being "frowned upon" doesn't do anything. There are people who play on this server who never rebel and have the only goal of helping the CTs in any way they can. They are going out of their way to ruin the game for their teammates. How is that justifiable? They're effectively teamkilling, but they aren't held responsible for it at all.

There are many players who constantly tell the CTs whenever one of their teammates has a gun, or where they are if they try to sneak off, or if they went in a vent, and so on - anything they can to prevent a successful rebellion. This is a team game, I do not feel it is conducive to good gameplay to allow terrorists to intentionally make their team lose every round. If they want to help the CTs win they should have to play as CT instead of ruining the experience for their teammates.
