At last ! Even Sunspots and comets are fermion repelling micro black holes ( Q-FFF Theory) So not only clusters eject micro BHs but all exploding stars if they had starspot black holes inside.
Dark Matter and Black Holes of variable sizes seem to be the same if we accept older ideas of Roger penrose ( The trapped space around the Black Hole repelling fermions. Q-FFF Theory)
and also according to the Hawking micro black hole assumption.
Then : sunspots and comets and the Kuiperbelt and Oort cloud represent such micro black holes.
Indeed the Big Bang seems the first COLD production of larger black holes before starformation.
