When making a plan, we don't recommend that you make concrete promises to your fans, such as, "I will always post one illustration per week".
Most creators think that they won't gain fans unless they provide special perks.
While it's true that some supporters may start following you in order to get special perks, your truly enthusiastic fans will be more interested in simply supporting your work as a creator.
Creators who spend all their energy making special perks to pursue short-term success may suffer burnout and become unable to post on FANBOX, ultimately betraying their loyal supporters. Beyond that, supporters who are only after special perks often lose interest quickly.
On the flip side, if a creator breaks their promises, supporters may feel unsatisfied, no matter how much they might love that creator's work. Don't make promises to your supporters lightly.
