You can make lots of money - just start a blog, scrape content from other blogs and websites, and add ads!This is wrong, for many reasons.
Blogger gives us the basic definition of what is not allowed, in Blogger Help: Spam, phishing, or malware on Blogger.
Spam blogs cause various problems, beyond simply wasting a few seconds of your time when you happen to come across one. They can clog up search engines, making it difficult to find real content on the subjects that interest you. They may scrape content from other sites on the web, using other people's writing to make it look as though they have useful information of their own. And if an automated system is creating spam posts at an extremely high rate, it can impact the speed and quality of the service for other, legitimate users.I summarise this definition, by advising you to publish blogs that are informative, interesting, and unique.
