I have run into the awkward situation, where I've posted a programming question, and received an answer, that I cannot apply due to project guidelines.
The account under which I posted the question identifies me, or at least for people knowing me, the user name would make it clear. Hence I don't feel comfortable saying "can't accept your answer, because of internal reasons" for fear of it reflecting badly on the company, or annoying my superior.
Now I am a bit stumped how to proceed. I cannot meaningfully reply to the answer, so I'd prefer to rephrase or delete and repost it. Rephrasing would however invalidate the given answer, and deleting answered questions is discouraged.
What is the best practice to proceed in such cases?
