I personally find knowing who favorited your submissions as a way to find new artists. It's nice to know who favorited and having notifications for it.
We're likely going to change the wording for this later. Currently, promotions will show notifications, but favorites won't; we are considering this more of a private way to gather art in a location. We will likely change "promotion" to "favorite," then "favorite" to "add to collection" to help make this clearer.
FN announced on Twitter today that favorite notifications will now be hidden entirely.
