Just a heads up. Plusnet has a parent safe blocker, safesearch. Used it for the last three years works great.
It's not been working for the last six days but Plusnet can't be bothered to inform us. I only know as a pop up from an innocent site was clicked on and now my child has seen hardcore porn. They don't seem to care and are not going to let people know that their safe search is no longer working. They don't even seem to care that my child has seen porn.
