Hello Dot Dot Dot, If you feel he is unstable then please reach out/quote DW directly. If you truly believe that, then that is the best way to help him.
Your reply seems like you have an axe to grind, which you are more than welcome to do so, but grinding your axe to everyone but DW, is not helping the mental state you believe he's in.
Btw, we are dealing with the matter internally through members reports, not everything is done in public eyes.
