This one does appear to be using an iframe, however scraping is an issue we've encountered before, and is certainly occurring for quite a few popular forums.
Warning: Do not, under any circumstances, log in using your AnandTech credentials on a site that isn't under the AnandTech.com domain. If you see a scraped version of the forums, do NOT attempt to log in "just for fun".
The objective of these scraped sites is often two-fold - one, to pull search queries from Google and generate revenue, two, to acquire login information from users confused about domains and use the data for phishing and other malicious purposes.
From our end, we'll work to get these sites taken down, but that can be a process in dealing with the web hosts where the illegal scraped forum contents are being hosted. In the interim, please avoid them at all costs.
