Is this a name and shame? I'm not sure that's going to be kosha with the forum gods.
If this is about known game-sploits, again, I'm not sure it's wise bringing it to attention. The less people that know the better (IMHO).
If this is about lame tactics...
A current popular server is full of tank bailers, stay in your god-damn vehicles and die like men! It's so irritating to have put rounds into the side of, say, a Panther, only to have the driver bail and you get hit by his backup without any kill.
A current popular server is also full of bush scanning irritating c***s. The tactic of pointing your vehicle gun at a line of bushes and scanning the bush or area by repeatedly clicking "enemy spotted" until the red "?" icon turns to "o" a red dot. Chat spamming pushes typed squad orders off the screen, remember that.
