As long as you don’t question that the enemies of US imperialism deserve it you should be mostly fine. The big geopolitical topics are more sensitive.
I was permabanned from multiple subs for sharing this telegraph article for example:
It differs from sub to sub but the bigger and more political the stronger the imperial narrative is enforced.
r/worldnews is one of the worst, and honestly suspect its astroturf and run by assets or a derivative of an imperial institution (council on foreign relation, think tanks, the likes)
Thats frustrating
I second the notion that your ip was banned by nc’s brute force detection
The silent reconnects of a DAVx client on a phone could easily trigger this
You can whitelist your home routers ip in the config IIRC Maybe not on the LISO container though, IIRC it is less configurable, but doesn’t “just work”, I’d ditch that not nextcloud
Quick fix could be to “DELETE FROM” (or “TRUNCATE” if you are certain nobody is blocked correctly) the table bruteforce_attempts (or smth similar). Although that “dc up && dc down” worked could indicate another issue, as you do seem to have persistence with your db in a docker volume (cred are still there) which would mean the time penalty ran out during restart or oits somethimg else
