.. Until she discovers those shit groups on Telegram and despite I warned her she continued.

They should be called newbie scamming groups, would be far more accurate.
But I find the article pretty weird, after all:
Starting with Shrimpy, there are now intelligent tools which can automate the process of getting signals for your portfolio
So, we're replacing the old scam filled telegram groups with industrial size newbie shaving facilities?
Anyhow, other than theory and fancy wording I don't see any real metrics that would point to those groups dying out, just another disguised publicity article.
Signal groups in a way, function similarly to pump and dump groups.
They's don't just function similarly, it's the same thing, but Signaling sounds better than Pump&Dump, just as ICO and IEO sound better than "Buy a Shitcoin".
