I think the bans that have been made in the past here demonstrate that there is considerable grey area over what constitutes 'abuse'. BlackMaze was banned for his heartfelt plea to change the planet tech simply because he had the temerity to name one dev specifically - despite the hundreds of posts made here in which people refer to or address David Braben. 'Moderation' like this is arbitrary, and reflects more what the mods are tired of hearing than any set of criteria for decency that they're supposedly upholding.
Hopefully, anyone in this conversation is adult enough to know where the line is; to play the ball, not the man, as they say. But the behaviour of the mods here in the past increasingly suggests that, while you may have a clear idea of what 'abuse' looks like, their definition is considerably more fluid.
