It is common knowledge that telegram is a gathering place for scammers, I often get invitations to join groups that are not genuine,
if the group has started to overdo it for promotions or giveaway I have indicated it is a scam and was very careful and immediately left the group
That's right, and before we leave it's a good idea to report the group as spam and then leave, that way the group will be blocked by the telegram, although scammers can easily rebuild it at another time.
