1) Pseudonym support.
Attention dumbasses: stage names and pen names have been realities of the business of being an artist for over 2,000 years.
Creators are not shoe salesmen.
The most basic functionality of any platform that intends to support *creators* earning money online – the basic, rock-bottom, sine qua non affordance – is people doing business using pseudonyms.
What that ACTUALLY means is the platform has to allow creators (the people who charge money) to be PSEUDONYMOUS (to use their stage name or pen names) in all of their interactions with their patrons (the people paying the money), AND the platform, which is legally required to know the legal identity of the creator and have on file their relevant tax ID numbers (e.g. SSN in the US), needs to keep that legal identity CONFIDENTIAL.
