Every single occurrence of an abuse complaint will be handled uniquely by anyone that handles it. Who it comes from, who it is against, what the impact will be, what evidence is given, what 'testimony' is gathered. All of this will make each complaint new and fresh and will cause the resolution to deviate slightly from whatever policy is laid out. No policy is going to be one hundred per cent iron clad against all situations, nor should it try to be.
I will ban anyone an accuser says is just as myopic and, frankly, farcical as never investigating or listening to any report.
When studying history, there are levels of sources. I imagine the same extends to the legal and other communities as well. All that is being said, from what I can parse through the emotional knee-jerking, is that evidence from outside the game is treated below evidence from the game. It's still evidence, but it is not sufficient on its own.
