Moderated forum thread causing exception in Activity Story Stream

After getting a spam post and having it flagged as abusive, the post shows that it is unavailable pending moderation (as expected). However, users who have the post in their activity stream seem to be generating an exception:

UnknownException: An error occurred while rendering the 'story.vm' script from the widget 'Activity Story Stream' (ff79be4dcc9b4884bbf9a455ef5eb1c5) (The forum thread is currently unavailable because it is pending review by moderators.) 
---> NVelocity.Exception.MethodInvocationException: Invocation of method 'ActivityUrl' in Telligent.Evolution.Extensibility.Api.Entities.Version1.ActivityStory, template f:ff79be4dcc9b4884bbf9a455ef5eb1c5::story.vm Line 156 Column 82 threw an exception 
---> Telligent.Evolution.Platform.Components.Exceptions.ContentUnderReviewException: The forum thread is currently unavailable because it is pending review by moderators.

Is this normal, and if so, can I turn off this exception (since I don't really want to see how many users are trying to see a pending moderation post)?
