Too many "Direct / Unknown" views compared to dev.to views in stats

Describe the Bug

The number of dev.to views in stats is almost always much less than the number of direct / unknown views, even though no link was uploaded anywhere else.

To Reproduce

Upload a post on dev.to.

Expected Behavior

The number of views from dev.to is the highest, since it's the primary way in which posts are discovered.
