Well I just joined because I wanted to find out what I was missing out on!
Seriously, my sympathies to Tom. I run a couple of message boards, one on the contentious subject of foxhunting in the UK, so appreciate the difficulties you're having Tom! It's a thankless task.
But I honestly don't think excluding non-members completely is the answer. (It gives the trolls a kick, no doubt, to think they've pushed you underground, but if they want to find out what's being said, they just join up again under a different identity.
The message board software I use (Invisionboard) has very good IP tools which HELP detect multiple identities (although far from foolproof) but also provide a system which can be set up to keep new members 'on probation' for x number of posts. While in that group, they can be restricted from posting (read only), be put on 'moderator preview (that really p****s them off!) or excluded from accessing certain forums. It can be set to automatically upgrade people to the next level after x number of posts - but of course if they cause trouble in the meantime, a moderator can suspend them indefinitely. (which stops them using the same e-mail address to re-register - AND keeps their IP on file for cross-checking.)
I don't know what this software's capabilities are, so I may be teaching Granny how to suck eggs - but hope you get it sorted! |
