People are always finding different ways to gatekeep people out of fandoms, or do a fan check, because you will never be a bigger fan than I am.
Every hobby has their annoying parts where people get too worked up over things that nobody else cares about. I collect vinyl records and people get livid if you bought one from Walmart. Sure we both own the same exact pressing, but I can’t be a part of your club because I didn’t buy that album from a mom and pop store.
I remember people on MAL getting butthurt over users not using the correct software to watch their anime. God forbid you installed VLC.
