I had covenant eyes for a while and I can say 3 things about it.
1) It monitors and rates everything you do. If someone who you would be embarassed in front of is reading the reports you have nothing to worry about. When choosing an accountability partner be sure to find someone who is a bit tech savvy and can know if you were playing around but got around it.
2) I found a way around it. I called them up and they said they were working on the problem. But that was only the accountability software - no the filter.
3) Often the reports came back saying "close review suggested" when in truth I did nothing wrong. My wife was the parter and she got a bit "uneasy" until she actually went to the sites that the close review originated from.
I now have k9. I have never gotten around it althought I have found some sites I wish were blocked. I can block them as time goes on.
Anyhow all the best for now.
