For charged black holes, supposing true the cosmic censorship conjecture, this inequality must be verified (in natural units):
$GM^2 > Q^2$
Where of course $M$ and $Q$ are the mass and charge of the black hole. Now suppose you "throw" a bunch of charged particles into the black hole. I know that the definition of charge and mass of a black hole is complicated and I know almost nothing about those. What I know is that they are usually defined based on their asymptotic values far away from the hole.
A quick google search seems to tell me that a particle falling into the black hole cause its mass and charged to increase of the mass and charged of the particle.
Does this mean that the inequality imply a limit for the mass/charge ratio for charged particles? Because if there's no limit one could keep throwing particles with a specific ratio until the inequality is no longer true creating a naked singularity.
