Good point, wouldn't say archiving is unethical at all...I was thinking more along the lines of someone scraping a entire segment of a websites data and reproducing it 1 for 1 on their own site with zero value add.

I think we can't make broad statements saying that web scraping is ethical or unethical, it isn't that black or white. It really depends on what is being scraped, how is it being used, and the intention of the scraper.
