Internet Positif is an Indonesian internet-filtering service that the Ministry of Communication and Information uses to block websites about topics such as gambling, pornography, phishing, racism and incitement of religious antagonism, or proxies. But because popular websites such as Reddit also got blocked, there has been much protest against the service and its initiator, the then-Minister of Communication and Information Tifatul Sembiring.
As of August 2015, Internet Positif has officially blocked Danbooru from Indonesian access (it can be circumvented through proxies, though).
Most notable for providing inspiration for the character Ipo-chan.
