Hi @julian, we were dealing with a similar issue. We have started to use post queue and the number of spam posts went down.

The screenshot you posted here looks good. Is there any way how to turn it on already?

And is it possible to approve the user, not just a post/comment, so that next time the user posts/reply, it doesn't go into the post queue?

I know that this can be done with reputation, but you don't get reputation for just posting/commenting.

Thanks!

We did this as well, but some of our moderators don't want to upvote posts that are not worth upvoting. They want to keep the value of their upvote
