Thanks for your response. I understand that my public IP in my router can be changed by DHCP release and renew so that is not the issue. My router is WPA2 protected and passphrase protected. In addition computers without listed MAC address are filtered out. So a neighbour breaking into the system seems unlikely, especially a friend. My daughter has denied doing this and frankly I'd be flabbergasted if she has! Which is why I am seeking an alternative explanation. If it is her she won't go on MSP for avery long time if ever. And she adores the website, so I need to be certain. She has a friend bear by but it is extremely unlikely her friend would want to do this, she is a genuine friend.
I have a dynamic IP address but I'm not sure I want tochange it now, especially if my daughter is guilty. Everything points to my daughter doing this, sigh! There is no possibility of anyone else in the home doing this. The only other plausible explanation is that she did it with a friend from her computer,but she is still implicated. Do you think hacking my network is unlikely, how unlikely?
I just can't believe it, she is only 11 and the appalling language used by the numerous banned accounts was advanced ( mid to late teen). I didn't think she was aware of most of the terms and innuendo used.
That's great advice, I didn't know about the key logger. Presumably all I have to do is download the software to her laptop? Incidentally I forgot to mention that I also have family safety and this has registered a huge number of hits for MSP, over 5,000 in a week before being blocked, which I thought suspicious. MSP assures me this is due to their flash player. Could you comment.
Furthermore all of this has caused me to reflect on security and identity theft and confidentiality. I thought I had done more than enough, especially compared with many. What do you think of a VPN such as hotspotshield to safeguard security. Are the VPN's themselves safe and reliable?
