Best practice: Temporarily revoke writing permissions?

[Shortround]

Hello.

I am quite new to NodeBB. Is there a best practice or a proposed way to temporarily revoke a user's permission to post to the forum? Only allowing reading for a certain amount of time?

I saw that a user can be banned (= from logging in) and I can also set a timer when the ban is being lifted automatically.

Is it easier to edit the single user's permissions or is there a quicker way using groups - although thinking of the situation - after a certain time of hour/days - when the permission are given back and the user is allowed to post again.

Thanks in advance!
