Our personal data, although a part of society does not stop to think about it, is one of the most valuable things we have as individuals. Personally, I would never share my personal data with any company or people I don't know, as my personal data will probably end up being part of a long list of data waiting to be purchased on the dark web, and we already know what this data is usually used for: phishing, scams, identity theft..., it is something I see every day. I think it's better to get money to invest in other ways, but as always, it's a personal choice.
