According to the Open Observatory of Network Interference (OONI) report (via BoingBoing), it has revealed that T-Mobile USA Web Guard is blocking a number of unexpected sites, including a Japanese URL shortening service, a Chinese sports news site, and even the sites for Cosmopolitan magazine, gaming portal Newgrounds, and the Internet Archive: Wayback Machine.
T-Mobile Web Guard is designed in order to restrict sites which comes under 12 different adult categories, including alcohol, pornography, and suicide. Its Web Guard FAQ explains that the “filter is not error-free and may over-restrict or under-restrict access from the customer’s (or parent’s) perspective.”
