pool.hdesknet.com.br is part of the fix-website-errors.com by Semalt SEO content scraper campaign, huge and very annoying. I wish they would just stop scraping my site. This botnet is huge and does not seem to want to end. It started with keywords-monitoring-success and free-video-tool.com, which then involved Virtua and megared.net.mx. The vast majority of these content scraper bots reside in Brazil and South America, but there are others from Italy and the US.
Thankfully, only one ip range kills this.
