That's not the only copy of the answer that was deleted. You pasted an identical answer on many different questions. It appears as if you were just trying to be helpful, but - if the same answer can sufficiently answer multiple questions, those questions should be flagged as possible duplicates and / or merge candidates.
If, in the future we were to merge those questions into one, six copies of your answer would then appear on the same (merged) question.
The moderator that deleted the posts was not taking issue with their quality, it was quantity that was the problem. The moderator that took action was just responding to a flag that the system automatically raises when it detects duplicate content.
I have restored the original answer on your question, and will look at a possible merge between all of the posts you found where it applies.
