Although I share your opinion related on a couple of exchanges from your list, I've never published a list like you do.
And you know why? Because I have no proof.
And while "a hunch" will make me avoid some exchanges, it still needs solid proof to accuse somebody/a business.


So I advise you show proof for your accusations. It will make them more credible and you also have your back secured against anything strange (lawsuits, trolls, name it).
