publish a suspension dispute policy

Reticketed from #2125.

I was thinking that we could collect an extra $15 from the user as insurance against a chargeback ... but then of course the $15 would also be stolen. :-/

I want to explore the possibility of having an open, public review policy for those that are willing to submit to it.

👍 I think having a publicly available dispute policy would be a good idea

Closing in favor of #2125.
