Well it would be nice to have an independent plateform to track and compare review process of the different appstore. Maybe EFF or a news outlet could think of that.
As a developer you may not have enought follower to publicize widely but you could fill a report. Theses report could then be audited by the independent plateform to label claims as legitimate or not (and maybe publicized or not).
I acknowledge this is a huge work, but this would be a good way to make a strong case and eventually go to court together. Collecting anecdotal evidence is not enough and is always biases toward publicized cases.
