Tracked another scraping bastard that uses a blank user agent from the IP address of 18.104.22.168 which appears to be a Lithuanian scraper/spammer with a dedicated server at HostDime.com.
Here's a few of this assholes active sites:
4-dates.netSome of them may look almost legit at first glance but trust me, there are tons of keyword and phrase stuffed bullshit pages hiding behind those seemingly innocent facades.
All the AdSense accounts claim to be owned by sunshineholidayrental.com which currently seems to be a Joomla default site.
Blocked HostDime a while back, looks like it was a good idea.
