I remember getting the occasional spam, and actually out of curiosity seeing how they would even complete their objective. Their objective? Sell you something that they are advertising. Many moons ago, I got one spam that had an 800 number. I called it and I couldn't even leave a message since the mailbox was full.
Spam = advertising. Advertising leading to the sale of a product or service. I noticed about 99% of the time there was no logical or easy way to make a call/visit a site,etc to present me with a product where I could buy it. You think grandma is going to de-obfuscate a URL(like slashdot's stupid email addy obfuscating filters) , visit the URL & buy your fake Lewis Vitton bags or whatever. Some spammers I swear are just spamming for the sake of spamming. Where's the money in that? There's ways around that like recommending I buy some junk stock that will be worthless in a month.
Then there was some Chinese individual who personally spammed me trying to sell me electronics. I carried on a good convo with him for a week until he told me to go to hell for wasting his time. He refused to tell me how he got my email address. In a funny coincidence, my gmail got hacked, sent spam mail out to everyone in my address book, including the spammer. He replied back saying he wasn't interested. yes, spam emailed spam.
BTW slashdot quit forcing me to preview, wait 2+ minutes to make a damn post on here. Or should I just go to reddit?
