> I don't think that's a reasonable question, not all scammers are Nigerian.
Than a non-sequitur, why would it matter? superbugs that originate in hospitals can escape and cause harm beyond a hospice; and if certain locales, Nigeria being the famous example of, are harder to touch, then those places will be selected-for for by scammers.
Consider that certain places are harder to police than others (which is basically the whole premise of this thread in the first place - than the EU is better policed than the UK); or that criminal operations could operate somewhere other then their place-of-origin.
> Some are based in the UK, others in Europe.
And if the European ones are more likely to get caught, there will be fewer of them, and a lot of those that remain won't operate locally.
> Also the EU had data sharing agreements and collaboration outreach
I don't doubt data-sharing is more difficult, I question if it makes any (long term) difference to remote (i.e. over the phone, or email) scams.
The question is how does that data relate to catching scammers who trivially outsource from elsewhere? Does the EU have any data on which EU companies run scams out of Nigeria[*0]? Even if the EU has a data-sharing agreement with Nigeria, I doubt the government even keeps tabs on the scammers. Plus, you can always move to wherever there isn't such a data-sharing agreement e.g. somewhere semi-hostile/antagonistic to Europe.
[0] SIDENOTE: I would mention somewhere other than Nigeria, so not as to seem to "pick on" the place, except - 1) Nigeria is established as famous for scams already, b) that would only make me more susceptible to downvotes from people triggered by me mentioning their somewhere-they-hold-dear in a negative light.
