In the mean-time, this is available for free for all
Linux users and it is completely under your control, but you MUST be a power user:
http://www.securemecca.com/
http://www.hostsfile.org
It consists of three portions
1. A pseudo HTTP Daemon
This handles the requests that are redirected to yourself.
2. A blocking hosts file
This only handles things that drop through the PAC filter
3. A PAC filter
This is the portion that does most of the blocking.
We will be providing it in French soon, but there are huge holes in content and we only attempt to block porn and gambling / gaming. That isn't just for content. The primary purpose of the hosts + PAC is to not only block content but also block sites that damage machines (Windows) or do exploits that will work on all operating systems. I will see if that one person who recently installed Ubuntu still has it on and if they do I will merge in the install code for Ubuntu. That install will also probably work for all of the Debian-esque flavors but I wouldn't know.
It's weakness is that there are huge gaping holes in terms of content. There are more false negatives than false positives. But it is better than going without anything. But the positive is that unlike everything else
it speeds up your Internet connection. In addition to blocking content and sites that damage it also blocks some of the most notorious spy domains on the Internet. That is the reason your connection speeds up.
There is no install for Ubuntu yet, but the Fedora / RHEL install should work with OpenSuSE with few if any modifications. I will try to find somebody who has Ubuntu and complete the modifications for the install. But if you Ubuntu people want to volunteer to give me what works then I will just merge that in.
Sites that damage Windows machines or do exploits on all systems receive higher priority, and if they also disseminate gambling or porn they are enemy number one. Hey, it is better than going with nothing. Just because
Linux is safer than Windows doesn't mean it doesn't need protection in addition to blocking content.
