the concept is very easy integrating badges related to every tv show let’s take game of thrones for example :
if episode marked as seen after 48h of the episode air date the badge would be
Quick Watcher every badge should have 3 stars each star given for 5 episodes if watched or something else based on the show max episodes more example below
Marathoner can be given if watched 3 episodes in 24h
Serial Commentator on commenting less than 1 hour after watching each episode
Mr Clean when progress is empty and u have nothing left to watch exclude hidden
Stalker if u have check another user’s profile
badges can be shareable
i’m just talking about an idea in general it’s not a must have i’m sure if u find it interesting u can discover more badges to implement this forum is doing great on badges so would be nice to have that in app too
