social_stream table very large size (18mb)

I have installed EasySocial on another site that I am developing and noticed that while a lot of users are logged in as admin, editing and creating articles (com_content articles), the social_stream table in the db became very large, almost 18mb!

I am guessing that all of the activity within the article manager was being tracked and recorded in social_stream?

Is there a way for the stream to ignore certain users or certain activity? For example, don't track super users within com_content or don't track com_content at all (No updates for new / edited articles).

Thanks for your help as always!
