You should not be on the panel if you start with a premise that 50% are false. You are impartial judge who with preconceived ideas. If the IPs mach and are from same ISP (not proxy or tor), close date/time, the probability is close to zero that these are fake flags.
Right. Let's form the committee from people who are blindly agree with every devs' decision. That the way to go )
The question isn't about blindly in agreement with dev, the questing is about looking at evidence with open mind without pre announcing that 50% are false (which for what I have seen of evidence, is impossible)
The thing is I suspect they used the same logic as you "IP and login date/time is pretty solid" while the only solid evidence is several payments from the same wallet. Everything else is guessing.
