Joining a public Telegram group carries no risk to your wallet or device by itself. The real risk in crypto groups is social engineering — unsolicited DMs from fake "admins" offering deals after you join. Computer Science Indonesia is listed in our directory, but the rule applies everywhere: never respond to DMs from unknown accounts after joining any crypto group. Your phone number is never visible to other members unless you've made it public in your Telegram privacy settings.

No. Telegram never notifies your contacts when you join or leave a group. Other members inside Computer Science Indonesia can see your username only if you post — your membership is not visible to anyone outside the group.

Computer Science Indonesia is a Telegram group for anyone interested in such-as-software and hardware. Members can expect regular discussions on networking and computerscience, along with software to discover.

We verify every listing is publicly accessible, has a minimum member count, and exclude groups Telegram has marked as harmful.
