@ZippyZiggurat @drekly, it's called create incommings by surveillance advertising, I call it Spyware as is.
They sell your data to third parties, which apart of a violation of your privacy rights, is a big security risk, nobody can control how your data is traty and protected, several cases of dataleaks with even bank and medical data prove this. There are other methodes to create incommings which don't invade privacy.

Not this way
