Am I subject to the EU's General Data Protection Regulation law?

So... my wife is freaking out right now.

She maintains a blog on the google site "blogger" which is a blog hosting service.

The EU's GDPR law basically says you cannot collect any data from a website user without informing them it is being collect. Her blogger site has, for instance, a comments section where you need to put in your email address to comment. So now she is terrified we will be "fined" if someone inputs their information on her blog and they are not warned.

I've tried explaining this 3 ways...........

1. She has the blog but Blogger is the host. It is THEIR code that collects the data, not hers, and therefor it is Blogger's responsibility to comply with the EU law, NOT HERS.

2. If Blogger is not in compliance with the law then the EU would fine Blogger's parent company, Google, not the owner's of individual blogs. Blogger "owns the code" everyone uses and they have to input the warning into their code/terms of service to warn people.

3. Even if the EU somehow took issue with her individual blog for collecting data, who gives a fuck? As I tried to explain to her she's a US citizen and the EU cannot "fine" her for having a blog not in compliance with their law. I kept asking her "Who is your representative in the EU that you would appeal to regarding this law?" I said the law is completely unenforceable for her because the EU has no standing to impose any kind of fine or penalty on a US citizen UNLESS it is a situation where we extradite someone to another country, which isn't happening over a blog lol
