For someone who frequents most major eastern news, i could say that Sankaku has been generally accurate for the past 2 years or so, other than that anyone with half a brain and is use to these would quickly figure out an inaccuracy rather easily.
SankakuComplex claims to be a website about anime and japanese video games but most of its content is about pornography or perverted eroticism. But what is probably the most annoying is the number of shameless comments, some are homophobic, a lot are generally very sexist. This place lost its sanity. Not children-friendly, and not friendly at all in general.
Full of sensationalist, biased articles. Contains badly researched or outright made-up information and some racism. Posts copyrighted content without marking the sources.
(Also, not for kids due to adult content.)
There are some hilarious articles on Sankaku, while other articles are just intriguing. Definitely a great place to read up on Japanese anime, manga and video games. This site is NSFW though and is intended for mature audiences.
This is an excellent website with fascinating stories, and links to the original news articles, and very-well drawn hentai. Definitely not for kids, though.
