I came across this while reviewing in 10K+ queue, had 2 x not an answer flags on it and I was just about to flag it as it has invalid flags but then..
Up until now I would have said it's an attempt to answer the question (poor-quality) but still an attempt. It's not spam, no hate speech, not a racist comment, none of these...
Personally, I wouldn't have deleted this answer but it actually did get deleted by a mod (and not community)
AFAIK, moderators don't delete answers based on the correctness of an answer but rather based on spam, link-only to another SO answer, etc.
So why was this one deleted?
