It is a PUBLIC forum - the online equivalent of loudly telling your business in the pub!
Journalists have ALWAYS got lines on stories from gossip, leaflets, overhearing things - this is just the modern equivalent.
Wanting a change to this I kinda understand BUT I think it's unrealistic to attempt to control the WORLD WIDE web. The technology would be a nightmare to design/implement even in supposedly closed countries like North Korea and China they haven't managed it.
Honestly this is why schools and youth organisations end up teaching children Internet safety because too many parents are clueless.
None of the reasons you give for THINKING you had an expectation of privacy make ANY sense.
In addition nobody is FORCING you to use mn. It's a choice, just as its a choice to use FB, Google or email (also NOT private btw - think that will come as a shock to op)
A choice to read, post on, post truthfully on mn. Choices have consequences - most adults get that.
I'm also surprised you think loose women is live or remotely credible journalistically speaking! It's a fluff show.
Weezol I've had "interesting" conversations with my mother re loyalty cards which she is convinced are purely to encourage you to shop at that shop. But yet she won't even use phone banking because "I don't want my bank details on some computer somewhere" - no amount of evidence I've shown her will convince her THEY ARE ALREADY on some computer somewhere. She's in her late 60's though and not a tech type person. I'm also bewildered by those 50 and under who are shockingly naive about the Internet.
The content also - makes NO difference legally! And actually on Reddit people post just as personal info if not more so.
