I certainly can do if that's what other posters want - I don't have any "skin in the game", so it's probably more useful for other posters to comments anyway. I do, however, see value in constantly challenging unsubstantiated claims - otherwise the claims become normalised and they appear more believable to unsuspecting punters (for the same reason I think repeated warnings and links to similar discussions is useful).

(As an aside, I also differentiate between knee-jerk responses to trolls - not at all useful, it's what they're looking for - and holding shills to account for what they've claimed - it tends to be exactly what they don't want).
