Blocking game from Son

I would like to block my son from using Second Life. He has been grounded but i still suspect that he is accessing it. I would like to ask what ports i should block or what ip is should block? I dont want to disable his internet entirely, but i just want him off the game for a little bit. Can someone please help me?

For starters, if you think he's using your account, you should change your password immediately to something he won't guess. And if you think he's signing in on another account, then you could contact our Support to have those accounts disabled.

Also on your end, since you are a watchful parent, there's parental control software which prevents using specific applications and could restrict opening Second Life. For example:

Take care, Superthrust!
