Spam/Junk Mail

[orchidsarefun]

I must get at least 30 junk mails every day - most go to my junk mail inbox.
I have always wondered what is the point of sending out e-mails that contain just links or nonsense. Does someone pay for this "advertising" ? If so, they can't be getting any return because if spam filters are detecting them, then only the foolish are opening them ?
Hopefully someone here can give the reason/s. I am sure that literally millions of junk mails do the rounds every day. Are these created by bots and then ping from server to server ? How do they find e-mail addresses to send to ?
