But what harm can it do, if you know all this information? What are you doing to do with it?
I get the point about identify theft, but that's the only difficulty I can see.
Personally what I might do is add as a friend on facebook and send a message of support, and supply an email address and say "email me if you want to reply to my message, otherwise sorry for the intrusion, I really appreciate your words about xxxxxx on yyyyy website. take care.".
Were I a nefarious character I might wish to abuse them online or (potentially) dox them or stalk them.
I know more since I last posted (having scrolled through other posts of theirs) - I know roughly when they bought their current home, I know that they have done a loft conversion and I might know what street they live on based on the GPS tracking on the photo sharing website.
Cross-checking the 10 or so houses that sold in roughly the right time period on that street with which ones have loft conversions, and then checking they were done since the purchase date could narrow down where they live to one or two possible houses. If I was an abusive ex I might even be willing to repeat the process with adjacent streets if it turns out that the GPS locator on the photo sharing site is poor. Or just hang out from 7am to 9am outside the nearest station.
TLDR - be incredibly careful about what information you give out online... and remember that persistent people can link lots of different things that you said over many many years. "I live in a 6 bed detached houses in a small village." "I paid over a million for my house". "We had a big extension done last year". "We've been here for exactly ten years". "My kids headteacher is well known locally for the way he dresses up for the Summer Fayre and raises a fortune by making a total fool of himself". "Our nearest town is XXXX Town about 8 miles away". "I just love the shops in YYYY town 13 miles away and go there once every month or two". Each thing is pretty innocuous, but if someone starts putting things together and turns up at your front door...
