i'm not defending anyone and i said nothing about "like" or "happy" in my post.
i'm telling you what the protocol says and that is what google follows as a matter of first resort.
every day i see urls indexed that 302 to other urls.
"some day" google may replace those urls in the index.
if those were 301s from the start they would not be indexed in the first place.
every day i see urls indexed that 404.
"some day" google may remove those urls from the index.
on the other hand, i don't recall ever seeing a url indexed that responded with a 410.
