A surprising connection between the weak gravity conjecture and the weak cosmic censorship has recently been proposed. In particular, it was argued that a promising class of counterexamples to cosmic censorship in four-dimensional Einstein-Maxwell-Λ theory would be removed if charged particles (with sufficient charge) were present. We test this idea and find that indeed if the weak gravity conjecture is true, one cannot violate the weak cosmic censorship this way. Remarkably, the minimum value of charge required to preserve the weak cosmic censorship appears to agree precisely with that proposed by the weak gravity conjecture.
