Some time ago I noticed that scraped articles that are republiched on blogspot have an author tag added to them giving credit to the blogger (=scraper). I think these tags are added automatically by the blogspot software. I wonder what would have happened if I were a member of G+ and had put my own author tag on these articles before they were scraped. Would the blogspot software replace my tag with the scrapers?
Edit- Now that I think about it, these scrapers probasbly don't copy the source codes of my articles, so any author tag that I added would be lost anyway.
Edit again -- I'm sorry -- My memory was totally confused. It was canonical tags, not author tags, that I noticed that blogspot was adding. Sorry.
