Activity Limits settings limit rapid actions like publishing, commenting, or private messaging within short intervals in your community. For example, if a member attempts to publish or send private messages or post images too frequently, they will be temporarily restricted, ensuring the community remains focused on meaningful engagement rather than automated or disruptive behavior.

You can find this setting under Settings > Moderation > Activity Limits.

Below is a screenshot of Activity Limits feature options:

There are three sections under Activity Limits:

Default Limits: These limits are set at the community level and apply to all members.
Select Edit for Default Limits to enter activity limit values. A window to enter the number of posts at various intervals of time opens. In the Duplication limit in 1 hour field if you enter:
- 0, then there is no limit on duplicate posts. Members can post any number of identical posts.
- 1, then no duplicate posts are not allowed.
- 2 or higher, then members can publish up to the specified number of identical posts.
Role-Based Overrides: You can specify specific roles from your community and set different activity limits. For members with these roles, the limits defined in this section override the default limits.

Select Edit for Role-Based Overrides to enter activity limit values. In the Apply only to following roles field, add the roles that should have different limits from the default.
Role Exclusion: You can specify community roles whose members should be exempt from activity limits. These are trusted members, or most often, Admins and Moderators. Also, when added, all members with these roles are automatically granted the Bypass activity limits permission.

Select Edit for Role Exclusion to add roles.

Note: The Bypass flood control permission that was introduced in Aurora version 24.12 is now renamed to Bypass activity limits.
