I do this sort of thing to mask my identity.

GMX, yandex, I’ve used them all without living in the countries they call home.

In the early 2000s I was probably the primary user of britneyspearsemail.com despite not caring about this celebrity at all.

I have a GMX account and I'm neither. A few decades back they were one of the few free email providers offering POP3 access.

I'm pretty sure created a gmx.de account around the turn of the Millennium and I'm not from a German speaking country. They had an email service and I needed an email.

The problem with absolute statements is that they always get it wrong.

The interesting thing is that satoshi was using a gmx.com address, emphasis on the .com. Those were only available to paying customers of GMX.de.

So GMX might know who Satoshi is but... GDPR?

Most likely they know who paid for the address. I need to check if payment via credit card was an option in 2009 or SEPA only.

IIRC, the gmx.com address was registered again later by someone else.

Either way can be traced

Very much not true, I'm neither :)

>Nobody in the world has GMX email addresses except the Germans and the Swiss.

You can just make one, right?

Almost nobody knew about them outside of the German areas

I'm neither and I did, so...
