Slow one viewer down
Their new comments wait for you. Nothing they've already posted is deleted, and they aren't banned.
Use case
The same viewer keeps crossing the line after several of their comments have already been held.
Put them on probation. The tray holds their new comments for review for as long as you choose.
You make the call from the viewer's page. The tray can also start probation by itself once it has held someone's comments on Auto, but only if you switch that on in Settings. It's off until you do. A dated probation lifts itself. An open-ended one stays until you lift it.

Outcomes
Their new comments wait for you. Nothing they've already posted is deleted, and they aren't banned.
Pick 1, 3, 7, 14, 30, 60 or 90 days, or leave it open until you lift it.
Read their comments, the reason for their current standing, the names they've used and what's been done about them before, then decide.
The path
Review the comments and moderation history the tray still has.
Give a reason and choose how long. Leave "Also hold their earlier comments?" ticked and the tray also holds anything it has seen from them in the last 30 days, within its usual limits. Whether the tray may start probation by itself is a separate choice in Settings.
New video comments can be held automatically, subject to Pause, YouTube quota and recovery checks.
End it early, or let a dated probation lift itself. An indefinite probation stays until you lift it.
