Rav Moshe Weinberger in this shiur, available for free, said the following:
“People would like to install Yiras Shamayim. You can’t do that, you can’t install Yiras Shamyaim, that’s the only problem. You can install a filter, but the person is the same person sitting down to the computer.”
He then expands this idea about the filter fixing the internet, not he person. Someone who has a teiyvas beheima (physical desire) for something isn’t going to be stopped by a filter. Rav Weinberger believes that we have to address the person, the pnemius of the person, Kedusha of a Jew and expose the greatness with each of us. Gevaldik!!
