Depends on what country you're in. In Saudi Arabia, all pornographic websites are blocked. A few years ago one of my then-employees went on the Hajj to Mecca. He told me that one night he was bored in his hotel room, and decided to check out some porn from his laptop. Instead, he was automatically redirected to a patriotic Saudi propaganda site. He tried other porn sites, and the same thing kept happening.
So easy to get around that stuff: Proxy server.
Find a proxy server that is not blocked and pass traffic through that proxy.
It won't work for dynamic filtering or filtering for specific words (I'll let your imagination figure out things on that last one.)
There's also encryption and remote access options, as well. You could remotely access a terminal in another location (a location that is, preferrably, not blocking what you are looking for) and use the internet freely from that remote computer.
There is also P2P sharing that could help one avoid censorship. Actually, P2P is probably the easiest way around the blocking. There are also FTP, SFTP, and TFTP options as they most likely wouldn't block most protocols.
The most hilarious option is hiding images or data with steganography.
Almost all of my ideas are sh*t if they block almost all traffic that leaves and comes into the country.
