We get substantially more GitHub stars than anything else, but what we are actually interested in are using that are actively engaged. Even though the activity weight for a GitHub stars is set to 0 it still reports as most of our activity for the month.
Currently the report building has the option to show only GitHub stars, but it does not have the ability to exclude them.
What would be nice is to have a more comprehensive report builder to say. "Type is not: GitHub Star"
