Communities are no longer restricted by walls or boundaries. People from all over the world can congregate and share their thoughts and opinions from the click of a button. A site owner has an inherent responsibility to protect users and prevent unwanted content. The chat filter is your first line of defense, but when multiple languages find their way in to the community, it can get confused and create false positives. Filtering multiple languages at the same time can quickly turn your leading advocates in to antagonists.
1. Word Collision
Word collisions occur when filtering multiple languages from a central black list. A word in English does not necessarily mean the same thing in German or Spanish. Filtering words and phrases in multiple languages within one community will create false positives. As an example, the word pupil (the center of the eye) is harmless. When an “a” is placed at the end, “pupila,” it becomes derogatory. The sequence of letters placed within a word can mean something harmless in one language and be profane in another. Be aware of the users in your online community and refine your filter based on the languages most commonly seen.
