How does that happen? Does the game include information about which account downloaded it? Because if so, it could probably be removed to avoid that.
Right, so. The launcher you use to download the game from Patreon saves information about your Patreon account to your computer when you login to enable the download button. The game itself (which is entirely separate from and doesn't actually need the launcher to run) will look for the information the launcher saved, make some local validation checks without verifying directly with Patreon (aka no internet needed post-download), and then load the pre-title splash screen. If those checks fail, you get a warning screen about not being a subscriber instead of being able to play the game.
Basically, for the Patreon version, the choices are the following:
- Upload a copy of the Patreon version without this information. This copy will not work for people who download it, and depending on how thoroughly you cleaned the game directory, may wind up getting you banned anyway because account data also gets saved in there by the launcher.
- Upload a copy of the Patreon version complete with subscriber information. The Patreon account gets permanently banned from subscribing to Team Carnal, and you're out however much money you paid to subscribe.
- Find a way to bypass the checks the game makes, such that a functional copy of the Patreon version can be uploaded without compromising a Patreon account.
Notably, this measure is very clearly a deterrent rather than a standard DRM measure. Copying the game in a playable state is very easy to do, but doing so involves personally compromising information that you're better off not giving away to the public at large.
All that said, it's basically a moot point at the moment because we're also behind relative to Steam. And Steam versions don't have any of these issues.
