Reminder: Lonely people are often easy targets for scams, finding comradery and social interaction as excuses to do things they wouldn't normally do.
If you, or someone you know, has been scammed by groups like the one posted above, it is Highly recommended that you alert others to this fact.
Again, grooming groups and those who prey on the socially removed will often make re-accessing their groups more difficult once their actions are exposed.
All of that aside, this is self-promotion in the form of advertising, and telegram scams are hugely prevalent right now. This whole post smacks of scam spam, and has been duplicated (as well as removed) in multiple other subs.
