Just that really. Don't get me wrong some times the op is clearly a troll/attention seeking. Fair enough, but in other instances the op is clearly stressed/worried and makes a mistake and certain posters start tearing the op a new one, Nothing constructive to add to the post, and will post 3 or 4 times pointing out the mistake, even when the op corrects themselves.
For example a post the other day the op mis-labeld a member of her family she said "my aunt" instead of my sister or my daughters aunt. And that was it, posters pecking at her and generally being nasty and horrible because in her worried/ stressed state she wrote the wrong thing. It did make the post confusing but even after the op corrected herself people still kept asking why she had made such a mistake, why did she say aunt and not sister etc.
Another one today. Op stated she had gotten some information from A. But she made a mistake, she got the information from B. It doesn't make a difference to the ops' original aibu where the information came from. Yet posters are again demanding to know why she said A when she actually ment B. It is clear the op is under alot of stress and not having a good day. She has corrected herself and apologised for the mistake. Now posters are demanding to know why she made this mistake, and why B has given her this info ( again where the info came from is irrelevant to the original post). It is very sad to read some of the comments.
Why do people feel the need to do this? Especially when it is clear the op is struggling. It just derails from the thread and usually results in the op not getting the advise they came for. It is a anonymous forum, does it really matter if the facts are exact with perfect SPAG as long as the post is understandable (and not a complete piss take)?
