Being one of those mentioned in your first paragraph, I have made posts before that could be deemed inappropriate and childish. Although most of these will likely be tongue in cheek (minus a smiley) or just plain humour to me, I do respect that others will have a different viewpoint to this, and have found myself apologising to Mods on occasion when I realise I've been guilty of breaking a forum rule in one way or another.
Though I have had run ins with Mods before, I can honestly say I can't argue with any of the reasons I've had for Warning Level being increased, and would even say there have been times I've expected an increase, but Mods have looked over it. This is good how at times they will show a degree of leniency to users IMO.
New users of all ages will join the site all the time, and it is important everyones points of view are respected and tolerated by posters.
They do a thankless task, and for that I'm sure 99.999% of CTO users, myself included, are grateful, and hope they keep up the good work.
