# Face – control
Face-control – helps to fight spam in your Telegram channel and does not miss users who do not meet your requirements. The bot ** processes the nicknames and descriptions of users ** and compares them with the conditions for passing Face control.
Depending on the settings, the bot can ** skip the user ** into the channel or immediately ** block him**.
You can set a number of conditions for checking the user in different categories:
Conditions for name verification: checking for the content of various characters, hieroglyphs and regular expressions in the name.
Conditions for checking the description: checking for the content of various characters, hieroglyphs and regular expressions in the user's description.
Другие условия: проверка на наличие username, аватара и настоящего имени.
