This video demonstrates base blocking using a tank.
Note that the tank is moving even though no one is in it. This prevents the tank from respawning so the block is permanent.
This is the reason we kick or ban players from doing this. It prevents access to the flag and is considered to be unfair play.

This is an example of spawn blocking. Although it's annoying it is allowed. The tank is not moving on it's own and will respawn if no one gets in it within the time limit. It is considered to be a tactic. No punishment is required. You can kill the player and move the tank yourself, you can even do the same back to them
