Ok, so I was thinking, if charge is conserved in the singularity of a black hole, you could have a black hole with a net charge one way or another. And then you could treat the black hole as a charged particle and in a binary system it could actually produce an em-wave. Then thinking further if a net charge did exsist the EM is strong enough to attract the opposite charge and the black hole could not maintain a net charge for a long period. But if it was in an area isolated enough to have a charge for some extended period of time, then would it become suicidal, that is would Hawking radiation kill it more quickly to even out the charge, in turn making it less massive, and in turn making it more likely to radiate. Just some thoughts.
