Not a lawyer, but have family that are: according to them it's really really hard to get disbarred. Permanent disbarment is basically reserved for stealing client money. Everything else is forgivable.

I was thinking the same thing, it's the type of thing that probably should be reported to the relevant bar. I don't know if it would get him disbarred, but there might be other disciplinary actions they can take if proven or it happens constantly.
