At risk of what, exactly?
The only difference between here and the DM is that most people won't admit to being regular forum users, whereas people are more likely to admit they read X article in the DM or similar. But from experience more people read MN without contributing than we realise, and if you put enough information on here which would identify you then there's as much chance that the people you're writing about will recognise you.
Six years ago I walked into my local tesco, and a woman at the till said "hello, you're wannabe from MN aren't you?
and I hadn't even opened my mouth. It was a well known fact though that I am VI, have one child, have a guide dog, and once I posted about something in my local area, and she recognised me purely from that information - she was a mn'er not someone who knew me personally, but the principle still stands.
People need to get past this idea that MN is a source of support for people to post their most intimate issues, about their DV relationships, abuse they may have suffered, about their mental health etc. Yes of course if people feel thus inclined they can post about those things here. But they do so in the knowledge that the instant they hit the post button that information is out there on a public website, and even if it isn't lifted by the tabloids, there is still no way to control who reads it, and digests it, and potentially recognises someone they know from it.
The daily mail lifting threads hasn't changed that fact at all. it's just highlighted it.
It's very simple. If you don't want your personal life to become public knowledge, then don't post it on public media.
