It's your community, so you decide what you would like.
I have nothing against a moderated thread.
But there must be a clear policy, delete, say, only rude messages or accusatory posts without any arguments.
Especially, as you said, you value their reputation and I think you will not abuse the moderator rights.
Yes, very good point.
What I would like to really do is reduce noise. I don't mind scam accusations and all that stupidity, but not the same posts repeated over and over and over
For me. Anything goes so long as it is on topic and has some argument. I also dont have time to be baby sitting the thread, but in the interests of peace...
Of course, lots of people say moderated posts are the sign of a scam so cant win there
