Ask HN: My domain registrar (Hover) rug-pulled me for $3000

I registered the domain onlyfans.sexy ~6 years ago as a gag where I'd post pictures of fans (everything on the site and in this post is SFW). This year I got an email stating that, like all prior years, the domain would auto-renew at $38 in seven days and didn't think anything of the next two emails also notifying me that the domain would auto-renew. It would seem that I very much SHOULD have paid attention to those next two emails, because in both the three and one day renewal emails the price changed from $38 to $3000. Needless to say, I was surprised when I was billed $3k USD (plus tax). After contacting Hover's customer support, they told me that there was nothing that they could do about this and they have a no refund policy because "Hover does not have the ability to override or reverse pricing set by the registry. Premium domain pricing, including renewal costs, is determined by the registry, and they may adjust those prices over time. Once a renewal has been processed, we are charged that fee immediately by the registry, and those charges are non-refundable to us." So according to Hover, the .sexy registry (Uniregistry) sets prices as it sees fit, decided to jack up the renewal cost at the last minute because they can, and there's simply nothing they or I can do about it. Has anyone here experienced anything similar?
