Public of private navigation ? Proxy ? Free solution to not get caught?

Hi there,

I would like to know first of all if it is better to use Webscrapper in private navigation or public navigation ?

If i want to scrap a lot of data, what are the risks ? I saw for example that TripAdvisor has a click tracker on Email, how to avoid being caught scrapping by TripAdvisor ?

I heard that a lot of people use Proxy or VPN. Is there a free solution to be protected while scrapping ?

Thank you very much for your contributions,
