Police officers stop many bad people. In 3 months they stop nearly 10000 phone numbers. Officers block 13888 numbers in total. More than 13000 numbers are from Germany. 491 numbers come from Austria. The action has a name. The name is Operation Herakles.
The bad people use a trick. The name of the trick is Cyber-Trading-Fraud. They promise high profit for money. Victims pay money on fake web sites. Then false brokers call the victims. They want more money. At the end the victims lose all money.
Many offices work together. The agency Bundes-Netz-Agentur helps too. The agency tells phone firms to check buyers. Bad people get no new numbers now. Investigators delete over 2000 fake internet addresses.
