Hi Alchemy
Many thanks for your post. We are so on this as I find it frustrating and to be honest very upsetting - some of the posts have been offensive to say the least.
Over the holidays we have trialled several approaches:
- approving users before they can post - this slows down responses enormously and is less than ideal so I am loathed to make it a permanent feature
We have however:
- added hidden anti spam measures to the registration form, quick reply area and main posting area fields - these are helping
- banned the repeating territory offenders - this is also helping
About to:
- limit the number of posts per user until the first is verified - which is where we are now
If anyone has any ideas more I would love to hear them

please do post on this thread. We are open to all ideas.
Thanks again Alchemy,
Annabel x
