Personal information on internet

If I think about the risk of share my personal information on public websites, I could be paranoid and imagine that I have a psychopath looking for my location and who is my family or something else. But usually I don't care about it because I prefer stay away of this preocupations, and because I think that exist a huge amount of people that share more information of themselves. Anyway, I hasn't share enough information to do so much. But, I has be precared naturally and I think isn´t necessary show my ID or adress. Maybe I feeling more vulnerable with my "hidden information" and what they can do the companies like Google or others with that. Because I have linked all my accounts with Gmail and from there I probably wrote anytime my ID and adress. Also, they know my likes and then show me publicity about that.

My favourite social media is facebook because there I have access to memes, culture information, funny videos, events, diffusion groups and chat at the same time. But I don´t trust in the intentions of the owner of the company, so I limit myself to using it in banalities.
