Regardless, there are a lot of fraudulent and misleading companies US-based companies that should probably be shut down.
Are you confusing cold calling with spamming? Here, for example, is the SEC page describing rules that cold callers need to follow: https://www.sec.gov/fast-answers/answerscoldhtm.html
I think the post you were replying to was saying cold calling in Germany is illegal full stop. I don't think that is the case in be US.
The problem is chasing companies not in US jurisdiction.
There is no technical limitation. It is allowed behavior and that must change.
No. It most certainly is not. It may be illegal in your locality, but it is certainly legal in most of the US. The federal Do Not Call list would be useless if it were illegal.
Now I get 1-2 a month from scammers abroad and with "private numbers" which is highly annoying since those aren't even legitimate. As a solution I asked my phone company to block all foreign numbers: won't do (they didn't say the couldn't they just won't). They also profit from you calling/accepting a foreign number so just get a fine from them and see how long it lasts would be my solution.
Hopefully the authorities and carriers can figure it out before it grows to US levels. At least they are working on it (English article from Dec 2021: https://www.traficom.fi/en/news/traficom-looks-ways-block-in..., latest Finnish technical recommendation PDF on call blocking from Feb 2022: https://www.traficom.fi/sites/default/files/media/regulation...).
However, I feel operators should start verifying these somehow. Or allow me to block all calls from a Norwegian number originating from India for instance if not in my contacts or something.
EDIT: I was just commenting on the physical geographic location of the callers, not anybody's race or nationality
Also, I once returned a wallet thick with various cards, all paper money already stolen but things like drivers license and other important documents still inside. I brought it to the police. I waited for almost an hour in line, and then it took more than another hour of the officer documenting every single item in the thick wallet. He had to, he could not just write "wallet", it had to be every single item.
I highly doubt the police will do anything. Scams don't seem to be anything the police will go after, maybe some very high level stuff when it's about millions. They are also very busy writing reports and doing other important paperwork... /s Googling I just found that there are 760 cases of bike theft per day in Germany. Less than a tenth of them are found. -- https://blog.alh.de/taeglich-werden-ueber-760-fahrraeder-ges... -- There is just too much "small stuff" for police. If anyone gets murdered I just have to wait a day or two for the newspapers to announce the murderer has been found. On the other hand, for small crimes I expect not much is going to happen apart from filing the report (which I'm sure alone takes up plenty of time).
I suspect virtually all such reports end up being used for metrics and no actual prosecutorial case is created out of them.
