Parental control

  I am pretty sure some of you people must have come across this problem. I will make a heart felt honest attempt to make you feel in my shoes. Right now I am in US and I have as sister who is in 12 years old. She has unrestricted access to internet. 

  Before she used to chat in facebook using other cousin sisters and brothers facebook account. She used to mostly talk with relative, family and family friends. Since people in the house didn't agree to make her own facebook account, she somehow managed to convince one of the far distant cousin to make her own facebook account. At first this looked like harmless and innocent act out of curiosity and it started from there. We clearly failed to see the signs at first, but then started seeing unwanted people pop up on her facebook account, wall and so on. So we decided to block facebook in both mozilla and firefox. And we thought that was end of out problem.. But then after few days we found her using facebook using google chrome. It was actually due to holiday season, that she had enough time and bit of negligence on family's part that allowed  her to get this technically sophisticated at this age. Other cousins in the house allowed her to use facebook saying that they would close it down after the dashain and tihar holidays...but i am feeling things are going out of control. Just a few days back I found out she had also managed to create a skype id taking help from someone else by convincing them that she had to talk with cousins overseas and it was urgent. By the time i was aware of this fact and asked my distant relative about this matter, she had already managed to change her skype password. My suspicion started growing. Then one of my cousin said she had blocked some unknown people on her facebook but she is somehow communicating with them. I can't do much coz I am not physically present there. And since it is a joint family there are lots of computers in the house. It is almost impossible to restrict her net use. 

  Finally I decided to take help of team viewer with help of cousin to monitor her browsing activities and my fears are slowly turning into reality. With help of team viewer I have found out that she has created a new hotmail add, and linked her facebook to new hotmail add...to which no has access or password and just her. I also found out she has several people on her skype account. Why in the world does she need a skype account??? I myself have 5 people in my skype account and use it with only close people for video communication. Most shocking part was that she was communicating with blocked people on her facebook using mutual frens and other girls on her facebook who are frens with them. 

  I am really baffled by her level of sophistication. I am also told there are lots of missed calls coming in our home in the land line. Though she doesn't have her own cell phone, i am doubting she does manages to get her hands on cellphone of other less tech savvy people in home like aunts and all, who have no clue. I did tell my other cousin to keep a close watch on her cellphone habits but they tell me she knows how to delete logs and clear history. Only once it was found..a delivery report to a unknown person..which she was unable to delete..due to late delivery. Upon investigation it was found it was a female fren. But later it was found it was same female mutual fren she is communicating to with blocked and unwanted people on facebook and internet. And some of those people do live around in close vicinty!!!

I was able to use teamviewer session only once and able to gather this info. But now i fear she does have some idea even about that. I also need to get more sohisticated than that.

I know I might sound bit of hyper and going out of line. But I can't help myself.
