Implicating 4_balls → multi_balls
Link to implication
Reason:
An alternative would be to alias it since I'm not sure that counting the number of balls is really that helpful tagging-wise. However, I'm not sure if the difference in posts is just because the tagger is thinking "there are only 3 balls" or simply "this is the only tag I know of".
For now at least I'm currently writing the wikis as if this implication were true; I can always change it later.
