THAT DAM FILTER
filtering means that all Internet traffic goes through the servers of the censor, who is
scanning the content for 'bad words'. This dynamic filtering is true for most filters in schools, libraries and companies.
If the site contains bad words it is blocked. The person who is offering the blocked information could prevent the censoring
by "hide" the content inside of images. For the user there is almost no difference, but it is difficult for a computer program
to "read" the text inside an image. Also SSL encrypted traffic (a URL starting with https://...) can't be scanned easily.
You can test which keywords are blocked on your connection on http://www.zensur.freerk.com/kword/
there you can enter the keyword(s) you want to test an click on "send" when you get the message "You entered [your word
]" in return everything is fine, but if you get an error message you know which words are blocked.
