When did junk mails become part of our life?

What is the point of all the pointless spamming. They all got deleted in the end.

It's a crime in which the criminal is also the victim (they lost time, didn't they?)

When have time become so worthless? Isn't that the only thing in life you can't buy with money?

We all live a limited time. Why waste our valuable life posting spams and deleting spams? Has life become so worthless?
