Hi Samuel
Matter of fact! That‘s what it looks like IMP is also (atleast attempting to be) doing. (blocklist.imp.ch)
I don't know this host.
https://refused.breitband.ch/ here you go, not a secret. Legal background explained.
This is the exact same behaviour as Swisscom in this case.
As required by law, implemented as (broken as) requested. Not a secret, all Swiss ISP are affected.
Mit freundlichen Grüssen
