Good move definitly. Who would have the Chutzpa to call someone asking to be able to view that sht? These things destroy many people, including young people who wouldn't be able to log on because of course their parents wouldn't do these things (but actually you never know with some of those idiots, but majority of course wont), also gambling destroys many families, sometimes also becaue of young people, and in Israel you can be in debt forever, their isn't the Bankrupcy laws that their are here. So definitly its the right thing to do.
About what is concidered porn- I think its obvious, anyone naked at the very least (thats what I think they are aiming at the minimum, but in Halacha its stricter, but if this is done its good enough.)
