Combot Anti-Spam System (CAS)

What is CAS?

CAS stands for Combot Anti-Spam, an automated system designed to detect spammers in Telegram groups. If a user with any spam record connects to a CAS-secured group, the CAS system will ban that user immediately.

Commercial use

If you want to use the system for commercial purposes including but not limited to your own commercial Telegram bots, we require you to place an active link to on your service description page (or bot description) with "Powered by CAS" or similar inscription which states clearly that CAS is used.


What Telegram groups are CAS-secured?
Any group which is using Combot can be protected by CAS. Additionally, developers can use CAS API to integrate it into their own bots.
How can I ensure I don't get CAS banned?
Don't spam.
If I'm CAS banned what does it mean for my Telegram account?
For detailed information on how CAS bans affect your Telegram account, please visit the I've been CAS banned FAQ.
What is the difference between a CAS ban and a group ban?
The CAS system reliably detects spam without human factor. While group admins may choose to ban specific users & report spam, group admins cannot CAS ban users. CAS bans prevent users from joining CAS-secured groups. Group administrators may issue a normal ban, but these are not as severe as a CAS ban. We cannot prevent normal bans at Combot; whoever runs the group can ban users for any reason they desire.
