I have only read the first reply. I didn't want to read all because it is to much , and I am inactive on forum mostly.
So :
1. In rules it says: No kill in gunroom! This means : Guns in a room - gunroom. Room is : a 3 or 4 walls with exit. For the platform.. Yes, it has guns, but it is not a gunroom, so you can kill on platforms but in gunrooms and buyrooms will lead in 60min. ban and more.
2. Spawn killing: It is not your fault you have awp and you can own many guys in 5 seconds. That is just a competition. Next round they will try to avoid you somehow.. I have been sacrifice of spawn killing which made me stronger to find ways to avoid it. So the spawn killing restriction is denied. You have spawn protection for few seconds.. The rest is on you.
Hope I was clear and didn't miss anything.
