It depends, can't really care to read peter's patreon but this is the idea: (Hentaisio as an example)
Each Patreon has its own content policies, and Hentaisio's is:
$1: Simple donation, nothing in return.
$5: Simple donation, Discord access.
$8: Simple donation, Discord access, you can vote on future card releases.
If you get the $8 plan, and Hentaisio doesn't give you vote power, or discord access, is a ToS violation.
If peter has $5:file access, password access. But you only get the file, then is a ToS violation. You have to give whatever you stated on your plans. There's loopholes, like "file", what file? well XD that's the thing, he can give you whatever file he wants to, you need to be specific on what you are giving in the plan. This exact same logic goes for Kickstarter, Kickstarter holds the money; if the creator doesn't deliver what they promised, the money is not given to the creator, but instead returned to the backer (this is a butcher explanation I know is more complex than that).
