Comment: object fails .  The black hole mass estimate is almost certainly spurious, this is an oddball quasar with a weird spectrum and the usual methods to get rough estimates of black hole masses probably don't work well for an object like this. Note that Kozlowski did not even mention this object in the text of his paper. Presumably if the author had thought it was noteworthy to find a BH with mass 10 times bigger than any previously known from direct dynamical measurement, he would have mentioned that fact in the paper. Instead, this is probably just a case of an automated measurement and mass estimate going wrong and giving a spurious outlier result. As such, this doesn't really even belong in the list of largest known black holes. This is not a reliably measured mass and shouldn't be treated as though it was
