The same is true for Facebook. My website and ad accounts were banned one day without a reason. They said it did not meet community standards. There has been no recourse since 2 years.
My website is still blocked by Facebook's sharing debugger and my ad accounts with balance in them have been blocked without a reason given.
Beyond that, the point is just to make them notice you, so anything might be good enough. Reporting to a regulator like the CFPB can also be effective if the case looks financey - I got my PayPal account back recently that way after they didn't like how I typed in a tracking number and banned me for life.
