The use of accommodation addresses is when fraudsters use an address to make it seem like a legitimate business is being run.
The accommodation address provides a front for the fraudsters and may be the address they ask victims of fraud to send money to.
Mass marketing fraud can include things like foreign lottery scams and advance fee fraud, where victims are asked to send an up-front payment or fee.
If fraud has been committed, report it to Action Fraud.
