Steam filters profanity and slurs by default in Steam chat and games that support the filter. If you want to turn off Steam’s chat filter, you can. You can even add your own personal list of words you want to filter.
This setting is available on your Steam Account Preferences Page. To access it, click on your Steam account name in the upper right corner of the Steam window and select “Store Preferences”.
Scroll down to the “Community Content Preferences” section. The options under “Chat Filter” control Steam’s chat filter.
If you would like to disable Steam’s chat filter, select “Do not filter profanity or strong slurs” under “Language preferences”. You can also select “Allow profanity, but filter out insults”.
The default option is “Filter profanity and name calling with” ♥♥♥ “or” *** “.
By default, the option “Do not filter text from my Steam friends” is enabled. Steam doesn’t filter offensive words your friends send in messages. You can uncheck this box if you prefer Steam to apply this filtering to your friends’ posts as well.
Under “Additional custom filtered words” you can fully customize the filter. To have Steam filter another word, enter it in the “Always filter these words” box and click “Add”. To make sure that Steam never filters a specific word, enter it in the “Never filter these words” box and click “Add”.
You can also download the lists as text files by clicking on the “Download” button – or download a word list from a text file by clicking on the “Download” button.
When you’re done, you can simply exit the Preferences page. You don’t need to click a “Save” button – Steam will instantly apply your changes.
