You are criticizing the verification system by comparing it to ProtonDB which, again, is a different thing.
Different in some ways but serves the same purpose.
Steam's verification isn't "inaccurate,"
Yes it is.
Crowdsourcing something like that would not be a good way for Valve to accomplish its goals.
Yes it would.
I did all of that in my parent comment. It's only stupid if the government can prove it's not true, which they can't.
