Pretty much as Panther says.
We, who are in this avenue are most likely not going to be overly sharing about information that has been gathered through a lot of trial and error. And I would be somewhat cautious of people who do, or at least urge to you get proof to not get scammed by bad actors.
I do heavily disagree with benbangor’s reply as many people are making a living off of this still, so that seems to me somewhat uninformed yet regurgitated opinion on the subject.
The real truth is, it is possible, but it is definitely more difficult than it used to be and unless you have a way in and understanding of what needs to be done, there are probably other avenues that are better earning and ‘easier’. Not to discourage though
