India is reviewing its ban on porn sites

This may be an underhand method to promote Indian content developers. Other than that there's no rhyme or reason to such bans.

In the 1960s they imposed a crippling tariff on Hollywood movies just so the government didnt have to take a stand on Indian moviemakers clamoring for liberalizing laws showing on-screen kissing and nudity. They felt Hollywood movies got away with bloody murder whereas what they could show would not even quicken the pulse of a nun.
