I've seen the leaked data posted on forums. I'm assuming they're trying to minimize the bad PR from this incident by only doing what's legally required, which is to notify affected users. They're likely not obligated to notify the broader public. Whether they should be obligated to do so is another discussion entirely.

Could you please tell me which forum this was posted on

I'm fairly sure even mentioning the name of the forum isn't allowed on HN. It should be trivial to find it yourself, though. I also replied to someone else with the CSV headers if you're only trying to find out what exactly was included in the leak: https://news.ycombinator.com/item?id=46932380

Also, keep in mind that this is a partial leak. The data was scraped from some leaky endpoint which was patched out before every user could be scraped. Only users who were in the partial leak received emails (I have two accounts, only one received an email). If you're a Substack user but didn't receive an email, I'd assume you're not in the leak. Troy Hunt should load it into HIBP eventually, and those concerned can check there if they don't want to seek the leak out on their own.
