Wordfilter - Definition from the Hotspot Shield Glossary
A Wordfilter is designed to remove any inappropriate language on the internet - Platforms that use Wordfilters could be online forums, chat rooms, messaging apps and comments sections on blogs and websites.
There are a huge range of word filters ranging from simplistic ones that simply search text for certain words, to mode advanced ones that consider the actual context of the supposed illicit word. There are word filters that specifically tackle swearing, filters that seek to eliminate spam, and filters that seek to remove overused terms like internet memes. While some word filters simply remove the offending piece of text, others will replace the word completely with something embarrassing, while others may change the text into non-standard characters like a hash.
