Scam exist everywhere, especially on the internet. Anyone is welcomed to join this forum, these scammers are only fished out when you and I report these guys or raise alarm so everyone will be aware of their tactics. The moderators cannot do it alone, they need the conscious effort of everyone to fish this guys out and ban them outrightly if the need be.

Pending when the admins do the needful, everyone should be careful of who they interact with; especially newbies who are usually the targets of these scammers. I bet you @op, if you were careless to join any telegram group, you would have been brainwashed further until you begin to feel it's too late to leave.
