"'deceptive practices', 'impersonation', or 'extortion'" - this, however, is your interpretation and it is taking it pretty far.
'deceptive practices' - that I can agree with. No matter how you do it, it is deceptive. Then again, a lot of businesses were built with (oh, say Airbnb or Youtube) / use (every cheap airline website) shady practices.
'impersonation' - does not have to be. What if they clearly list that this is not an official X site? If your data is public and crawlable, is it illegal for people to use that information?
'extortion' - does not have to be. Isn't this an equivalent of going to the same business and saying, I did a bit of research on you, then I told 3 people about you and they would love to buy your services. I'll refer them to you if you give me $5. Is this illegal?
