My Ko-Fi doesn't have exclusive content, I barely have the time to that haha
But I usually use it for both tipping and commissions, I have most of my work separated in categories in the Gallery, it's very up to date too, I also have a Shop where I drop the adoptables I design or some cellphone backgrounds.
I'm currently trying to reach a goal for a new Drawing Tablet as well, it's been going a bit slowly since there have been some extra spending (Health and now a new pet) but it's going quite well.
I plan to, for the day I decide to make stories of my own, to use the shop so people can download the PDFs or similar.
