i personally dont see how you can ban it. you would need a rule the clearly states how stationary jabs you can do before you are considered in violation of the rule before you enforce any bans.
From Sirlin about bans:
Enforceable
Sometimes, a tactic can be hard to detect. If you can’t reliably detect something, you certainly can’t enforce penalties on it. In a fighting game, a trick might make a move invulnerable that shouldn’t be, but actually detecting every time the trick is used might be nearly impossible. Or consider a real-time strategy game, where a trick might give your units a few more hit points than normal, but again, detecting this might be nearly impossible in a real game. If something is to be banned from tournament play, it must be reasonably easy to identify when it happens or to prevent it from ever happening at all.
Also in a fighting game, a move might be “unfairly” unblockable, but only when that move is executed in a certain situation with precise 1/60th of a second timing. Did the player execute it during that “unfair” time window? Or 1/60th of a second late? Perhaps he accidentally executed the move at the unfair time through sheer luck. Is he to be penalized? Imagine trying to enforce a rule that states “You may usually use move X, but there’s 1/60th of a second where you may not use move X.”
Discrete
The thing to be banned must be able to be “completely defined.” Imagine that in a fighting game, repeating a certain sequence of five moves over and over is the best tactic in the game. Further suppose that doing so is “taboo” and that players want to ban it. There is no concrete definition of exactly what must be banned. Can players do three repetitions of the five moves? What about two reps? What about one? What about repeating the first four moves and omitting the fifth? Is that okay? The game becomes a test of who is willing to play as closely as possible to the “taboo tactic” without breaking the (arbitrary) letter of the law defining the tactic.
Or in a first-person shooter game, consider the notion of banning “camping” (sitting in one place for too long). No friendly agreement between the players is necessary for the ban, which at least means it’s enforceable. The server can monitor the positions of players, and it knows exactly who breaks the rule and can hand out penalties accordingly. The ban is enforceable, but the problem is being able to completely define camping. If camping is defined as staying within one zone for 3 minutes, and if it really is the best tactic, then sitting in that zone for 2 minutes 59 seconds becomes the best tactic. It’s a slippery slope because there will always exist camping tactics arbitrarily close to the specific kind of camping that is banned.
Here’s an example of a completely defined game element. In the card game Magic: The Gathering, if a particular card is deemed to be too good, then it is possible to ban it. One can define completely that “that card cannot be used.” There is no fear of players still “sort of” using it, in the same way they could still “sort of” repeat the moves from the fighting game, or “sort of” camp for 2 minutes 59 seconds above. The card is a discrete entity that can feasibly be banned.
