I searched the keyword "SEO" and didn't find any match in the comments here, I'm surprised. For anyone who has been a webmaster, one can immediately recognize it's an extremely common technique in the blackhat SEO scene for decades, used by content farms everywhere. One just copies articles from somewhere else, replace all words with dictionary synonyms to evade the search engine penalty, and fill the resulted websites with spam. Perhaps it's not as popular in the English world, but common in China, and is a standard tool included in all blackhat SEO software. And no, it doesn't work well, the output is gibberish too in spite of the language differences. Oh, and the article says: > A high proportion of these papers came from authors in China. Exactly what I expected. The spammers found a new market, apparently. It's sad to see that some scientific papers and journals are literally becoming blackhat SEO spam and content farms.
