Yes I was aware of this misconception, but I was thinking that there could be strange effects, like tide effect ripping away the stars passing nearby. I was also thinking of the possibility of the hole getting wider transforming once stable orbit into non-stable one which will end-up inside the black hole. From what I've gathered, evaporation seems to be a really slow process. So I figured that it only gets bigger. The remaining question is how fast. We know there are very big black holes, though they were formed when conditions were different. I was wondering if there were possibility of a small one slowly by accretion growing into one, and was thinking maybe that if you are already very close to the black hole limit, maybe the neighborhood is also crowded and you could start a snow-ball effect. There is also the dark-matter/dark-energy issue if it exists, when you are a neutron star, you can pass freely but once a black hole you should collect it as you go.
