After going through a swift, awesome chat with support (kudos to George E.), I wanted to leave some constructive feedback for you guys.
It would be nice to have an option to set up a customized profile name regardless of login credentials; in case of people creating a Spotify account and then connecting it to Facebook, it would be nice to have more control over what information is pulled from the Facebook account onto the Spotify account: automatic avatar syncronisation would be nice (as in, if I change my facebook profile picture it syncs to Spotify as my avatar; unless that is already a thing) and, most importantly, an option to disable syncing my full name from facebook and applying it to my Spotify profile.
Also, I've been using Spotify for a while (free user until recently, now Premium :D) but I've never seen any of my Spotify activity synced to Facebook while I had the two accounts connected - ever! New playlists created/updated, new artists or playlists followed etc.
