Here are some ideas that were floated a while back and I wondered what the BBS community thought about them:
Don’t let a new poster post until he’s been around for n days (or some combination of reads/likes given/time spent)*
Comments don’t appear until moderator-approved (until n posts are approved or the commenter gains a trust level)
… to be clear, this is just blue sky daydreaming shared with the intent of gathering general feedback NOT any kind of remotely formal proposal, or anything that is on the drawing board for implementation.
I have my own ideas about this, but I want to hear yours first.
* This is technically already enforced for creating new topics, which you can’t do as a new trust level 0 user.
