ian - thank you for your reply. i take your point about the perception vs reality issue as far as answering the question if the mods have indeed been 'ham-fisted' in their judgement. if indeed the numbers do bear out your point then all well and good as that is what i was hoping to achieve as well.
however, this does not address the more specific issue of when a mod should step in. as esoteric a question like this makes a quantifiable answer difficult i'll grant you but nonetheless, does require consideration.
if we accept the premise that we are not children (well, save a few that is ..) then removing threads/posts will be seen by the liberal public as censorship which i am sure you will agree is a dirty word. nobody wants to be told what/when/how to do things and i only question the need for mods to step in (in certain cases) to begin with and then to what extent ?
some people have no problems with the actions so far and yet others are just asking questions. i do not doubt that the work the mods do is thankless and time-consuming and have been happy with the majority. i just hope that this question does not affect their commitment to do their best as this is an academic question at best.
i sincerely hope that this does not degenerate beyond this discussion stage as that was not my intention. i welcome all your input on this.
edited to add that i won't be necessarily adding to this thread anymore as all the necessary questions have been asked and some of them answered. a quick thanks to ian, keith and mawby for being open to discussion.
