This has been annoying me for 10+ years. I see this "as such" -- 
apparently taken to mean exactly or very nearly exactly "therefore" -- 
very frequently in on-line text, even that composed by otherwise 
apparently intelligent and articulate persons.

Does this "as such" = "therefore" appear in any dictionaries or other 
reference books?

Do teachers accept this in student essays and the like?
