i tag out when i can, but i have reasons for not tagging out/"ignoring" castmates on the same memes, like

- i know who the player is and i don't like their writing
- no permissions post (goes double if it's a shipping meme, triple if the canon/characters have divided fan opinions)
- they have a permissions post but we have conflicting prefs
- i've seen the account around and know they don't tag back
- it's me. i play both sides of a ship i like and i am not tagging myself
- did not see their comment because i don't always comb through memes before i top level and am unlikely to return to the meme if i don't get any tags
- don't feel like writing a starter

i hope this helps you understand your friends
