This ia huge clickbait sadly. It’s some random small oktoberfest, where some drunken germans maybe doing the Hitler greeting.
I’m not saying it’s okay what they do, but by far not world news. This would be maximum local news if at all.
But you cannot have your own domain on posteo as far as i know.
GDPR clearly says, if there is a valid reason for storing your data, they can store it (no timelimit). Like you can store data for invoices etc for 10 years too even when you ask them for deleting your data.
Iguesseverybody also agreed to it when you registered.
I do not see any valid reason why they would delete acvounts, like saving 1 line in a database?
Why? Just do not open profiles? And even if you do, why not just ignore the counter? I do not see any benefit in this function.
