Just that, really.
AIBU to think it makes perfect sense and allows a more realistic response?
An OP posts a question, asks opinion and advice.
People do them the courtesy of spending time thinking about it and writing an answer.
A poster mentions they've looked at their previous posts which contain a lot of pertinent info, back story, repeated incidents etc etc which weren't included in the current post.
This informs the advice they then give.
Why have I so often seen others haranguing them for going down the previous (entirely public) posts?
It seems very sensible - to get the facts before wading in to answer something that only gives a fragment of the true picture.
What do you think?
