Killfile for some users isn't a bad idea in principle, but if over-used it can lead to a very quite forum with just a few very learned (and quite dull) people talking about one subject only, completely unaware that beneath the killfile level (and of couse invisible to them) there is a vibrant community of people all chatting about all sorts of things, having a good time, making friends and just occassinally even talking about caving.
Speaking as someone who has a very clear idea of how much work is involved in adminstering anything like this, it is far easier to learn to skim-read and mentally 'killfile' as Peter suggested near the start of this thread.
Instead of Killfile you could always have an "opt out" policy where anyone offended by humour or banter can go to their own elite section where they can discuss bolting and lunar-influenced rope strains at a sub-atomic level, or kick the ass out of SRT theory to their hearts content, with absolutely no danger of humour rearing its ugly head.
Everyone I have met so far in the caving community has been a mine of information and a good laugh, whilst I appreciate some people can take banter a bit far (I have been guilty of a few karmic follies) Killfiling people because you dislike their posts or don't share a common interest is completely arrogant, skim reading and viewer's discretion works just as well. If you feel that you can't ignore someone without it being absolute and permanent, or at least tolerate them.. then perhaps it isn't them who have the problem.
Deleting posts is all well and good, but what is drivel to one person might be of interest to another... I like the banter and the quips and sometimes even the drivel is funny, if that is abhorrent then there is always www.google.com full of info and god forbid, no humour whatsoever.
Is it a problem that really needs solving? you know... all those bloody cavers having fun?
I hope not, I've seen forums die out because of folks no longer wanting to post due to heavy handed mods and asinine functions. Idle chat and the shit heap seem fine, why the need for change?
