# Discard Rules

It is possible to discard activities added to a feed based on certain rules.

### Common Use Case

One common use case is when users post in a feed that one of their own notification feeds follows. By default, the user gets a notification of their own activity. To avoid this, you can apply a discard rule so that the user's own activities can be filtered out.

### Parameters

The following discard rules are available:

| name                          | description                                                                                       |
| ----------------------------- | ------------------------------------------------------------------------------------------------- |
| discard_rule_default          | Discard when activity actor matches the user_id of the feed                                       |
| discard_rule_actor_with_colon | Discard when the second part of the activity actor split on colon matches the user_id of the feed |

To enable this feature, [contact support](https://getstream.io/contact/support/) with:
