Thanks for the questions. So basically I'm not sure how Patreon works yet. I have it for 3 days. If they ban me it is their problem and I will move to subscribestar. Also, I'm not sure if it charge you immediately because so far people subscribed to me and I cannot payout anything. I hope this company is not a scam. They wanted me to fill up some official documents so it's already shady.
About the benefits it is tricky. Votings should be ok but I can't provide much because Tax Offices in my country are considering it as sales and requiring you to start an enterprise (with all financial consequences).
If you have any ideas or suggestions on what would be better than Patreon, let me know. So far I used Ko-Fi and it was ok.
