You can find yourself being extradited. The legal grounds matter little, as you may find yourself in a Kafkaesque process that will ruin your happiness
I have ignored this for years when I was a digital pirate in Europe.
Fake DMCA bogus can also index you out of google, even your homepage where no 3rd party links are found if you don't fight them
I got lawsuits from the RIAA but non related.
You can safely ignore DMCA's if they're not applied to your jurisdiction, BUT your host and other providers won't when they go upstream unless they also are like in china russia or whatever ignores the US asks
I remember this case from the UK, well the five-eyes english kingdom is very strong in it's ties.
I only know of cases getting condemned in my country when they accepted dubious plea deals. Very few. Anecdotical.
I read somewhere if you think a law Is unjust, you must break it, but do so publicly accepting facing any consequences.
If extradition is on the table, and jail on the US, maybe we need some more martyr's to suffer through this to make a point that copyright is absurd nowadays.
Sadly that is nor good advice
