I don't know what to say any more Tippler. Where bank regulation exists, it is a shambles and the police are in a permanent state of re-organisation as one scandal after another affects them. The FSA has been replaced by the FCA for no good reason as part of a re-branding exercise and SOCA disappeared in mysterious circumstances.
In the past year one person was convicted of fraud involving over 750 bank accounts they opened and used for fraud and another person has recently been convicted in respect of over 100 bank accounts they operated in the same way, and these aren't a part of organised crime. The only people in the UK who appear unaware that our banking system has become the natural home for bank accounts used in crime are our law enforcement bodies who have announced recently that they have set up a department to deal with internet crime, as if they've only just noticed the burgeoning problem.
I've never used an ad site and never would as they're run now because, although I know enough to avoid most scams, I just couldn't be bothered to wade through them all looking for honest deals. Unfortunately a lot of people go on those sites unaware of the risks, and the more people who get burned by scams on them, the more those sites will just become thieve's bazaars. Honest sellers can't compete with the scammers and buyers are more likely to get burrned than get a good deal.
The banking deficiencies, making it simple for any criminal to open a bunch of fraudulent bank accounts, just makes it too easy. Currently it's a lot easier to commit crime, with little risk of prosecution, than it is to get a job in the UK. I'm sure that there are online guides detailing how to set this up, though the ease with which it can be done doesn't require any great intelligence or technical knowledge.
As this newspaper article states
.....scam 'so easy a child could do it’
http://www.telegraph.co.uk/news/worldnews/europe/10375380/The-33000-a-week-benefit-scam-so-easy-a-child-could-do-it.htmlIt will probably only be when systems start to collapse that anything will be done about it.
Whether those involved are UK citizens or not is irrelevant. It's just a lot easier if you are not a UK citizen and/or have many foreign contacts.
