A very random question...

Yes, this post has little to do with writing or art or... Anything of a significance deeper than burning personal curiosity.

I have grown to consider Spam one of the great mysteries of the internet. There is so much of it. Email, twitter DMs, even SMS... It seems to find one almost wherever one goes.

The mystery in it, for me, is how in the world is it lucrative? Wikipedia states, "Spamming remains economically viable because advertisers have no operating costs beyond the management of their mailing lists," but, be that as it may, surely it still takes a good deal of time to set these systems up? Or to run around Twitter spamming DM boxes? Someone must pay these people to do these things...?

And really, who will click on links describing things like how to meet amorous Asian girls, or how to enlarge one's genitals in a substantial and surely medically unsafe way, unless the person in question is both terribly insecure, and has been living under a rock for, oh, about 15 years now? Surely, all the time and effort and money of those creating these spam messages must be at least 80% in vain? How in the world does such a proliferation still exist? A margin of at least 15% of recipients who click by sheer accident...?
