If the case is genuinely unwarranted, it's relatively straightforward to garner public sympathy by providing a detailed account of the situation: the website in question, the products or services offered, what actions Stripe took, and what steps have already been taken to resolve the issue. This comprehensive information allows for a transparent evaluation of whether Stripe's actions were indeed unjustifiable.
If I were Stripe customer support reading posts on HN that would be the lowest bar to even look at it. The OPs post is in this bucket.
In instances where a post on Hacker News does convincingly argue that a Stripe ban is a false positive, I'm confident that the community would rally behind it. However, merely asking for a connection to Stripe support doesn't fit the ethos of Hacker News. Such posts are better served by sinking under the weight of flagged posts, as they don't contribute to the discourse that HN aims to foster. Hacker News isn't a shortcut to Stripe's customer service.
