In particular How to ask for a job referral from a person you don't know? where the top answer was changed after criticism and surprise that it was the accepted answer. (Albeit the question title was reworded as well).
The initial answer which was accepted was summarised in the line
"Don't waste your time, or theirs."
After being accepted the answer was revised. With the "edited" answer coming to a different conclusion:
"If you're really asking about referral, go for it;"
(NOTE: title edit was from "reference" to "referral")
Despite the fact I agree with the new answer over the old answer, the answer has now completely changed from the initial accepted answer. I understand the merits of improving an answer even (or especially) after being accepted to benefit the community. However this answer has not been improved but actually the intent changed. This is misleading to future people with the same question.
How should we respond to the changing of the answer? Or is the onus purely on the question asker to review the approved answer now it has been edited?
