Sadly, you won’t find much help on HN with this problem, and you can see by the lack of upvotes how much people want to hear about any problems that it causes.

Sadly, you won’t find much help on HN with this problem, and you can see by the lack of upvotes how much people want to hear about any problems that it causes. The overarching sentiment here is that GDPR is amazingly awesome and that no abuses of it are going to happen. Don’t have 100 hours to reply to each nightmare letter? You must be doing something bad with their data. This isn’t the first abuse, and it won’t be the last. Unfortunately, even if you’re not in the EU, you have optionally chosen to subject yourself to the GDPR under Recital 23 by “mentioning” EU users. You must spend the time to respond. The good news is that you can write it once and send roughly the same response to each abuser. If you don’t respond to their full satisfaction, you’re looking at immense fines. Welcome to the GDPR.
