The scammer's website is as plausible as a pantomime horse and they appear to be continuing the comic theme with laughable threats.
In honesty it would be more more threatening if they said they were going to tell on you to their Mommy.
The English on the website is diabolical and I doubt they could make much more sense to the Polish police, and for a company claiming to be founded in Norway and based in Poland nonsensical claims such as
Bank deposits and withdrawals are not taxable by UK law
What's UK law got to do with it ? - from a jurisdictional and legal point of view, and - it's irrelevant too.
I doubt that they're going to hand themselves in to the police, but this scammer could be that stupid to judge from his behaviour so far.
The scammers know that we can check and verify the credentials of any company claiming to be based in the UK or USA in the blink of an eye so they hope that by locating the fictitious entity in another country it'll make it more difficult. Actually it makes it easier as this only makes it immediately obvious it's a fraud due to the regulatory impossibility of any such company being allowed to operate, and the scammer hasn't a clue as to how to make it look plausible. Located in Poland with prices in US$ and references to UK law ? They've even left traces of a previous name they've used in their 'copy and paste' wording.
