No, no. You don't understand. Instead of creating ONE patreon account with 4 projects (3 finished), you create FOUR patreon accounts with 1 project each, all unfinished. With the first option you can get 5000 supporters in one account (for the unfinished project mostly), but in the second you can get 5000 supporters on each account. After all you will get no supporters (or maybe a few) for finished projects, if the underlying idea of a supporter is to help the dev update or finish the project.With the second option same supporters can pay multiple times, with the second option the can not.Okay, read again what you just said, but slowly. You can't subscribe twice to someone.
I completely understand and agree your opinion in the rest of your post, it is totally logical from the supporter point of view, but not from the developer side. If you have understood what I said now, it's pretty obvious the best choice for a dev, and that's very bad for supporters. Maybe some developers are too busy updating multiple projects (under different accounts) and that's why they update so late.
