Website censoration in Iran and Its solution
As you may know, in Iran the internet is censored, so a lot of websites are blocked, from Facebook to YouTube.
In order to access these websites, you will need something called a Virtual Private Network (VPN).
Facebook is banned in Iran, as well as Twitter, some Google services, the BBC, CNN. Of course porn sites are blocked.
On the other hand, this is kind of controversial because the ruler of Iran has an actual Twitter account and many Iranians retweet his tweets.
I know that this last thing may sound kind of funny but the fact is that, despite the censorship, almost everybody uses a VPN (Virtual Private Network) in Iran and the Government already knows that, but there is not much they can do about it. Yes, using a VPN is illegal but everybody in Iran uses it. VPN Apps for mobiles are accessible if you a little search in Google play.
