It took me two weeks, plus sending IDs, incorporating an ltd, to get a license to sell software with Paddle. With itch I just need a paypal/stripe account.
Apparently if you wanna send automated texts in America, you need a real phone number. And to not get immediately blocked, you need to fill out a form that goes to the major carriers for approval (like AT&T). And the form is not unlike Paddle's verification. You need a company, EIN, samples of what your texts will look like. Massive pain.
