This seems like a useless copyright specific padding tag. Following already exists.

I didn't know this tag existed. Pokemon following their trainers is a common topic of conversation in the fandom, but I agree that the following tag covers the concept sufficiently.

The bulk update request #25459 (forum #277919) has been approved by @nonamethanks.
