My dad owns a telephone company, he used to have an exchange that went through an indian reservation. He couldn't get rid of that exchange fast enough. People would go through and steal the copper out of the telephone line. In fact, more than once a couple of them died because they tried to steal the wire out of power lines.
And of course, my dad was blamed for service outages. WTH was he supposed to do? put armed guards up at every telephone post?
Of course, wire thievery has mostly stopped because of two changes to the business. The first, all lines are buried. People would rather climb 10ft up than dig 2ft down.. Go figure. The second is the use of fiberoptic cable.. Can't strip that out with a knife 😀.
