When I first started and came across this phenomenon, I decided to start a 'shite' list of people who quit on me.
I was playing Alt Sht a lot those days, and it was beyond tedious to have the same people quit all the time.
I had 100's of names on that list.
A leopard doesn't change his spots, or is it tiger and stripes, well u know what i mean.
Give the turds one chance and one chance only.
