... don't. That's what they want you to do. You quitting actually earns them more money, because they can cut back on server rent and they can lay off/reallocate some stuff members from the community managers. Instead, if you can still find any joy in this game and you really want to hurt them, just keep playing it casually. BUT DON'T SPEND A FREAKING DIME FROM NOW ON. Become a burden for them. Play the game as they advertise it with their actions... F2P. Overwhelm their servers until the whales start crying about the bad server stability. Thus they will have no choice but to put more money into BDO if they don't want to lose their precious whale population. Spread the word and rise up! Hurt them where it really hurts! Hurt them at the only place they care about being hurt. At their wallet!
