Thank you for your suggestion. However, these subscription platforms are not feasible for me. Patreon has permanently banned my account, and SubscribeStar's official team doesn't approve my monetization eligibility.
Additionally, the old products were created using outdated models, and given the rapid advancement of AI, they are now obsolete. I don't think there's a need to put these old products on other platforms as subscription content, nor is there a necessity to launch a bundle for purchasing all the old products at once.
My current focus is on launching new series and creating content that can be sold on DLsite.
Nevertheless, I appreciate you bringing up these ideas.
