I assume they won’t ban anyone automatically without a way to object.
Using your example, i wouldn’t assume they would enforce the ban if you object and explain your typo and if the corrected citation actually says what you cited.
Mistakes like these are explainable a completely hallucinated citation is usually not.
Yes. They record almost every talk. You’ll find the relive (unedited recording of the live stream) on https://media.ccc.de and some time later the edited recording also on media.ccc.de and also on YouTube.
There also also live translations to English (and some other languages) for talks in german.
It depends. There is not one Swiss German but multiple subdialects. The language spoke around the Bern region very far away from German while the one from Zürich or Basel is much closer. Since there is no official written from they never really converged to a homogeneous language.
You might want to try the Wim Hof Method. I don't believe in everthing Wim Hof attributes to his method but when it comes to immune response, there is scientific evidence that it does indeed result in an increase of IL-10, which is anti inflammatory.
