I found it on their FAQ.
Yes, it is generally less restrictive, but... I have 4 domains, and now I have renewed all of them for the maximum amount. They will all expire after 2033. So unless I decide to add more domains (which is unlikely), I won't spend a cent in the next ~9 years. I wonder if they really enforce it as it is written or they consider still the renewal an expense "split" over the duration.
Still, I really don't understand. You can - and should - have proper rate limits on the API. You have API keys that uniquely identify the source, what is "the abuse" they are trying to prevent this way...?
I also migrated everything to Porkbun. Gandi used to be good too, we used it extensively at work in my previous org (~3 years ago).
Is the whole sector regressing? It seems these companies aren't happy just earning a profit based on the service they offer. There is always something "more" that they need to do. Often this makes the experience worse. Meh.
Super happy with Porkbun BTW, it just works, does what it's needed and I found the renewals to be 50% cheaper compared to GoDaddy...
