Questions about moderation & features

[An_dz]

I have a few questions about NodeBB, though I'm quite sure about their answers I'll still ask in case there's some plugin or something I missed.

1. Is there a way to warn users and this show up for all moderators, like when flagging posts?

2. Like the above, can you make an user require post approval? Or even disallow to post? Both for a set time.

3. Can you prevent tag creation?
