Sure, I have no objection on that. The problem is that they don't communicate it and you need to guess. With Google, you don't have someone explaining you what's the problem and what you can do to fix it.
Right, and even if it's true that disclosing the detailed reason for a ban would hurt their security posture (I doubt it), I think in most cases it should be pretty obvious when the person disputing a suspension is just someone who got caught in the algorithmic crossfire.
But expending even the smallest amount of effort to determine that isn't something Google feels like spending time or money on.
