If I remember correctly, this stems from Angry Birds ads. Not sure if any other apps use it.

Even with an ad-blocker, the folder will be created each time the app runs.

 

There are definitely other apps that use it cuz I have it and I don't have Angry Birds on my phone.

 

So deleting it is not a problem then, right?

 

So is there a way to remove Angry Birds? It seems to be there forever, I have looked in the app system to clean off apps I don't use and it doesn't seem to be one I can delete.

 

Can you uninstall the angry bird app if you go into the app store?
