Broken locks, bed thefts, and safety nets

While I have read up on lockers and general practices about keeping valuables in hostels, I want to double check in relation to some things I have read in more recent articles. I have been told these days, in hostels, theft has been increasing because people are figuring out how to break the locks on lockers. In addition, I have also read reports of people not being afraid of taking things out of someone’s bed while they’re sleeping. Some have said get anti-theft safety nets for backpacks, but the average starts at $40 or so dollars.

How common is it, truly, to come across someone who is capable of breaking a lock on a hostel locker? Are travel nets worth it over a backpack? Are the reports of people taking things out of someone’s bed while they’re sleeping overly paranoid?
