Yeah. No. This won't work. Having a front man doesn't keep your computer from having all the files, with all the history of the work on those files. Then there's the IP address when you upload files to be downloaded, access to Patreon/Subscribestar, etc. If you are getting the funds directly from the platform, those records are discoverable. If you have the front man get the money and then funnel it to you, that is all discoverable. Your emails with them, your texts with them, your discord msgs with them, etc. All discoverable.
Even if you could "hide" all the evidence (not likely - since you're already describing this on a public-facing forum, you can't keep a secret well) --- if you are knowingly working for a company that is doing illegal activity, charges are always a possibility. The driver of a getaway car in a bank robbery isn't robbing the bank themselves... but they get prosecuted.
There are so many holes in your logic that a herd of elephants could charge through unabated.
If it's illegal, don't do it.
If you want to risk your freedom, that is your decision... but don't fool yourself.
Also, don't add other possible offenses that can be added to your charges if/when you are caught. In some countries, what you are thinking through may qualify you for racketeering charges on top of the porn charges. Even if the porn charges don't stick, they can still get you on the racketeering.
All for jack and shit for earnings in game development.
The media adult game developer on Patreon brings in about $100 USD per month after they have been developing for over 3 years.
Do you really want to risk all that for about $1,000 USD per year?
Just you
