This is one major factor that is making people to lose their money now. I got scammed in a group some few weeks ago because I was waiting to buy a project at listing and I was added to the fake group of that project unaware, I just went ahead and bought tokens through the link dropped in the fake group, it was too late before I realized I have been scammed. We need to set our privacy in such a way that we cannot be added to just any how group.
