There are several stop lists on the admin panel:

• Words
• Phrases
• Links
• Nicknames

Algorithm

The system splits all received text messages with spaces. For example, the user texted “And-after-all, you’re my wonderwall.” The algorithm sees this as a message with four words split with spaces: “And-after-all,” “you’re,” “my,” and “wonderwall.” Each word is checked with the basic rules of illicit language. If the system finds matches, words are restrcited from sending in a chat.

1. According to the list of replacement characters, each word is checked for matches with the characters on the list. The received word is then cleared of all special symbols, meaning all symbols except Latin script letters and Arabic numbers (i.e. %, $, _, <, these are examples of special symbols). For instance, ‘grand+ma’ is returned as simply ‘grandma’.
2. The original text (message) is checked for phrases that match the block phrase list via text search (somewhat similar to ctrl+f search). If such a match is found, the whole text (user message) is blocked, i.e., it cannot be sent to chat. The Block phrase list can only be accessed and edited by admins with full permission.
3. The text is checked with the Websites’ blocklist for full matches. The text (message) is blocked from sending if such a match is found. The Websites’ blocklist can only be accessed and edited by admins with full permission.

How to create such a list?

• We recommend covering key inappropriate language and topics

obscene language and rude words, words can be used for sexualized provocations, insults based on nationality and race, threats, insults or specific prohibited topics-words-phrases that are specific to the language, words prohibited in public space by local law.

In addition to the list of words themselves, you need to write down their variations: inflections for nouns, participles, adjectives, conjugations for verbs (if applicable).

It is also necessary for the most popular words to indicate generally accepted spellings (for example, replacing “i” with “1” or “!” and other frequency replacements).

Please remember, moderation works through complete matching: If the list contains the word "panda", the words "pandas" will be allowed.

• The words added to the list shouldn’t be homonymous with valid words.

Words that are homonymous or partially homonymous with valid words (when placing an obscene word inside another word makes it censored). This is especially true for short words-syllables, which will block the sending of censored words. Be careful!

(If you add the word “Mars”, users won’t be able to add “Marseille”).
