 ### Custom Events
 
-Google Analytics 4 has strict rules for event naming and requires you to adhere to those requirements in order to successfully send events. Segment will replace all spaces with underscores to ensure the event name adheres to Google's [event naming rules](https://support.google.com/analytics/answer/13316687?hl=en&ref_topic=13367860&sjid=2167389739796023681-NA#zippy=%2Cweb){:target="_blank"}. As a result, you will see custom events snake cased in Google Analytics 4.
+Google Analytics 4 does not accept custom event names that include spaces. Segment replaces spaces in the Event Name in the Custom Event action with an underscore. As a result, you will see custom events snake cased in Google Analytics 4.
 
 Event names are case-sensitive in Google Analytics 4. If you would like all event names to be lowercase, use the **Lowercase Event Name** setting when you create a Custom Event mapping and select `Yes` from the dropdown. If this setting is disabled, Google will treat event names with different casing as distinct events.
