# Automated Pre-Moderation

Based on block lists.

**Pre-moderation** is the first step in the moderation process. During this step, the system prohibits users from typing certain forbidden words or phrases in a chat. This is based on several lists that can be constantly updated. If a message is blocked from being sent, users receive a notification that the message has been restricted.

Block lists with words, phrases, URLs, and nicknames are available. Please navigate the admin panel > Pre-moderation section and add all needed words or links.

**Word Blocking list**> words without spaces.

**Phrase Blocking list**> words with spaces and special characters, and sentences.

**Links Blocking list** > any links. You can fully restrict link sending in a chat, or restrict just those that are added on the list. It is also possible not just allow users to send links in a chat, but make them clickable (to do so, open the Settings > Interface elements > Messaging).

**Nicknames Blocking list** > Users cannot use words from this list in their nicknames, but they can send them in a chat. These nicknames can be used by admins.

## Supported languages

* Arabic (Ar),
* Armenian (Hy),
* Bulgarian (Bg),
* Dutch (Nl),
* English (En),
* Finnish (Fi),

If you need pre-moderation for a specific language you don't see in the list, please contact us. We can prepare it after the free trial. Also, explore AI opportunities that work for a broader list.

When you choose a default language for the chat (Language > Localisation), you activate the chat interface and the default pre-moderation list. When you transfer a GET parameter with a new language, the pre-moderation switches to the needed one. 

You can check these lists and correct them by adding them to the visible fields.

So, if you want to control all stages of [pre-moderation](https://chatadmin.watchers.io/phrase-blocklist), you should:

* Transfer the needed blocking lists for languages, as shown in the image below

* After transferring (button UPLOAD) and ensuring that everything looks as you wish, you can deactivate the default verification of the words with the lists (it can be done on the [Functional Settings](https://chatadmin.watchers.io/functionalSettings?tab=functional_settings)).

At the same time, when you add words, phrases, and links to the pre-moderation lists available on the admin panel, they are restricted to any language activated on your chats because they are linked to your project.
