I hope you are really good at data manipulation, you can find 76 pages of webscrapers on fiverr
You can have a look there for some EU details : Web scraping and GDPR
Or here : Is Web Scraping Illegal? Depends on What the Meaning of the Word Is
Web Scraping looks more “unethical” than illegal BUT it depends on HOW you collect data and WHAT you do with after. Big Corps seem to not like it at all, but think they don’t do…purely naive…I think that is closer to " world wild legal job market reality" :
More, I dont want to turn it into a “debate” but, what the “law” could do against you if, for example, you are a russian, who scrap american website and sell data to chinese companies ? It can be different if you are a US who try to scrap facebook off course.
Extend it to “ethic”…it’s your individual faith (this point can be discussed but I think it’s not what you asked for)
If you really think you want to do “legal” money with, you could start to read terms and conditions on website and possibly, ask a specialized lawyer in this field from your country (still less expensive than a bad lawsuit)
Note / iiik sorry @skaparate I didn’t reply on right line
