phishing and blackmail mails. I just got one of each sort. The first tries to bully me into to transfering half a month's wages at once or I'll be sued for not paying a bill I never made. In order to pay I am supposed to klick a link. Ridiculous, of course, but also annoying as they have my address and phone number - a breach of privacy. A copy of this mail will go to the police's cybercrime department first thing on Monday.
The other mail claims I got hacked and must pay some bitcoins into an account or my computer will get shut down. Even more ridiculous but far less serious. The delete button will suffice for that one.
The problem is that the police can only catch the low budget stupid ones. The ones smart enough to send this crap from remote lawless places will never get caught. It goes with Darwin's theory of survival of the fittest. Plus the police have their hands full with more grievous crimes like cyber-terrorism and cyber-pedo-pornography. The Internet has become a lawless jungle of the worst kind.
