One quick thing here............You can't fix stupid.
Really.
I don't understand why anyone would want to try.
If someone truly believes they can make a profession out of something they have no experience or training in, I say let them go for it. The rational ones will see reason before getting too deep, but the others won't listen to common sense. They will either fail miserably (probable outcome) or become a success (doubtful). Either way I will get the same amount of sleep every night.
I'm not sure why so much energy is spent discouraging these people. Yeah, they're fun to make fun of on the intertubes, but why make it a crusade? Like I said before......
You can't fix stupid.
To address the inevitable "they make the real pros look bad" remark, no........ no they don't. What they do is show people that cheap photographers that advertise solely ln Facebook and Craigslist suck, you get what you pay for, and next time do your homework and get a look at a real portfolio first. Word of mouth is a fantastic thing in that word of bad business or shoddy product spreads like wildfire in any profession.
