How is it checking the bots ? Is it doing reverse dns lookups ?

Agreed. I use single file to download and the print as pdf

Is step 1 and 2 not reversed ?

Yes, and I have one. Does about 7K per month and has been doing so for over 2.5 years.

All you need is a niche topic, lots of content and possibly great knowledge of SEO.
