>>39557258From the very own User manual on Bank:
"If you run out of membership, and do not take your Pokémon out of your Bank, they will be sweeped (deleted) out of the server and will disappear forever. Nintendo advises the players to purchase a new membership "as quickly as possible" "
So far, people that have not renewed bank since ~5-6 months, have seen their pokemon deleted.
Before even spewing bullshit, learn to read the very own manuals that come embedded with your games.
