Agree. We did the same till found out that our daughter had been verbally abused by her classmates on their chat. The situation was awful and our daughter didn't tell us anything because she is a very shy girl. We also could do nothing with her classmates. So we decided to install the mspy app and record all those conversations. It was very helpful in that situation.
I want to help my brother to make some new friends in real life or to find a new hobby.
You see, the problem is that spending a lot of time in front of the screen means that child in not interested in his or her life and try to escape.
My parents are too comformists to establish trust relationship with him. So, it's my responsibility.
