The problem is not access, it’s unlimited instant access. We had to wait until our parents weren’t home to raid Dad’s stash. Or catch a tape from someone’s uncle at a sleepover. It’s a world of difference.

That being said, blocking is not the answer. Blocking the major sites just pushes people to smaller sites, which may be more likely to harbor revenge porn, underage content, nonconsensual content, etc.

My 3rd gen Moto G had a removable back and was also water resistant. Though I don’t think it had a removable battery.
