Here at PoSARC - Partners of Sex Addicts/Compulsives, we have been seeing lots of discussion surrounding Porn Blockers and software - based solutions to the problem of SA and SAC issues. Our jury is out on this, or rather...deliberating!
We do feel that manufacturers need to consider creating a designation other than a "kiddie, teenager or college-age" type of settings for blocking explicit material. We want adults to have input on their settings when they want to be on guard against porn themselves.
We have learned that MyPornBlocker.com and PageClean.com are two programs that don't infantilize the user with having to use kiddie settings when doing set-up on the system.
We have yet to road-test them or others to see what we think.
Calling software Family or Kid-friendly carries the potential to add to the shame the sexual compulsive/addict usually already feels anyway. Software solutions may be a necessary part of a person's recovery toolkit, and recovery consulting / coaching such as is offered HERE can help you set up accountability plans tailored to the specifics of your own situation.
