How do the different group pre-moderation settings work?

Every group leader can update 3 global group settings for pre-moderation.

Here's what each one of them mean:

First time poster

When someone creates a discussion in the group for the first time, their discussion will end up as a pending discussion and will need to be approved by a group leader first. Once a discussion of that member is approved, future group discussions of the member in that specific group no longer need to be pre-moderated.

Potential commercial promotion / advertisement

Group discussions created by members that potentially advertise commercially on FetLife will require pre-moderation.

Group Discussion Contains a Link

If a group discussion contains a URL, whether it's a FetLife link or an external link, it will require pre-moderation.
