Please add an HTML-rewriting feature into your proxy.
This will allow people to view pages that have been
filtered based on the content of the page. Say for
example the word "fuçk" appered in the content. The
proxy could detect this and change the word to "fu*k".
If possible the end user should be allowed to specify
which words should be changed. A basic list of sware
words would be helpful.
This would allow access to the whole web.
