If a casino has a community on Telegram, they have to be super active to be able to keep scammers away. It will be difficult considering the number of scammers on Telegram, but it will not be impossible to achieve.
Some methods that some casinos there use are
- The admins of the group vet users before allowing them in the group; it is a closed group.
- Strict rules and warnings that are pinned, like gamblers should not take seriously any message from anyone claiming to be an admin.
- Admins who are active to delete fake links posted by gamblers to lead people to another platform.
The problem here is that many Telegram scammers aren't even part of the groups in which they scam. Take impersonators for example, who pretend to be group admins or trusted group members. The moment you join or ask a question, you will get contacted over PM by such people who use similar usernames and pictures that group admins do. They will ask if you need help, if you want to invest, join a special group, etc., etc. Their tactics obviously work good enough, otherwise they would abandon the idea.
One way to fight them is to make Telegram groups and channels private. In other words, you have to join the group before you can see any of the messages or other members. Admins can then see your username. If you try to impersonate any of them, you get kicked out. If you change your username, a public message appears, and admins get notified about it. It's not perfect but it's better than nothing.
