I'm not all-too familiar with the professional competitive CS:GO scene (or shooters in general) but I occasionally play some shooters.
Now in professional RTS/MOBA tournaments the players are often allowed to ban certain elements of the game or some elements/strategies are even forbidden by the tournament rules. I wanted to know whether there are some specific rules in CS:GO tournaments that disallow the use of certain weapons and/or tactics (Camping/Bunnyhopping for example) and also if the teams have an opportunity to ban certain weapons.
