Maybe I just cannot find it. But I don't see an obvious option to warn a user but ban him. Is it possible somehow? I mean a button like so
Actually it is a regular practice for communities to warn a user before ban. It is also should be possible to auto-ban a user reached N warnings.
Full ban for a first time wrong behavior sometimes is really over.
Is it possible to make this feature?
It connection with this option, pre-moderation is often used. It means all topics posted by warned and pre-moderated user require moderator's approval before going public. So it should be only visible for mods before and mods should be notified on such content.
