I have insisted that everyone affiliated with our kollel having an internet connection enrolls in Webchaver in addition to whatever filters they may be using. Its psychological effect is extremely powerful. Your wife / chavrusa / chosson teacher has access to everything you are viewing and is tipped off if you are attempting to tamper with the system. It is in effect preventing yichud with the internet -which ChaZaL would undoubtably have prohibited had anything like the internet been available in their times!

Rav Yitzchak Berkovits, Rosh Kollel - The Jerusalem Kollel, Rav - Sanhedria Murchevet, Jerusalem

There is an international scourge attacking the Jewish People: this is the widespread addiction of men to pornography. This scourge threatens to tear apart the fabric of Jewish life.. This addiction has spared no class of Jews: from teenagers to kollel members, from office workers to rabbis, and from single to married men.

Rav Aharon Feldman, Member of the Mo’etzes Gedolei HaTorah of America

I doubt that at any time in our history has there been as grave a threat to the morality of our people and to the stability of the Jewish family as the plague of addiction to Internet pornography. It has ruined more marriages than anything. It has ruined families. It's been terribly destructive.

Rabbi Abraham J. Twerski, MD

Not a week goes by that I don’t have to deal with a Shalom Bayis Problem or a problem in Chinuch Habanim or Banos, or a very fine Bochur who will call me up – or at least what is left of a very fine bochur – calls me up crying, begging for help. There is nobody that can claim that either they’re not affected, or a family member, or a neighbor, or the chaver sitting next to them in shul, or the chavrusah sitting across from them in yeshiva. If you discounted it until now, you’re gonna have to take my word for it when I say that there is no single problem facing the yechidim in klal Yisrael and communities at large, there is no bigger problem than this. There’s a Chov Kadosh to do something now before there’s no semblance of Kedusha left in Klal Yisrael. And I don’t say that lightly. Keep in mind, the people who come to me are so frum and so upset about what’s going on, that they’re willing to talk to their Rav. That means that there are thousands of people who would never even speak to their Rav. I hate to sound pessimistic – but if you have unrestricted Internet in the house – Internet that is not both filtered and reported, I would say there’s a higher than then 90% chance that people have already been Nichshal in your house. And if it hasn’t happened yet, there’s more than 90% chance it will happen. And if it’s not happening at home, it’s happening in the office.

Rav Yosef Veiner, Agudas Yisrael Flatbush

The Internet is filled with immoral and decadent sites which have the capability of destroying one’s yiraas shomayim and tzenius rapidly, before one even realizes how entrapped he is in their tentacles. It exerts a powerful force over many people that - if left unregulated - has the potential to destroy the fabric of the Jewish home. There are countless horror stories about young people falling prey to online seducers and the tragic consequences of their encounters. There is no need to repeat here that which is well known and documented.....

A highly effective tool to protect users from Internet dangers is a computer monitoring system, such as WebChaver, which alerts an appointed monitor of any inappropriate sites visited by the user, thus creating a strong deterrent.
