Internet censorship is the way where webmasters can control their sites in which they take out the over malicious contents in it or just hide it from the under aged users.
The senate is starting to proliferate the “malicious” contents on every site that are on the ISPs inside the Philippines, but most people contradict with it because they might take out the contents that are morally unacceptable such as government critical essays, adult-only-arts, or even the addicting MMORPGs.
China has laws on internet censorship, but these laws are not nationwide. Most pornographic sites are banned from a city, but sometimes the same site is allowed on another city.
In Singapore, internet censorship is taken to the fullest importance, because the populace is very conservative. Not only pornographic sites are banned, but also political, racial, and religious content are also not allowed in the ISPs of this country. This is done to avoid upsetting the delicate multi-racial society.
Last, in Myanmar, since its 2007 anti-government protest, the government completely shut down all its internet sites.
