they weren't a big ISP but they were (in some ways) a bit like a small version of Zen. Respect was/is due to both.

Metronet used to have an optional web proxy server. If you wanted to ignore it, you could.

It didn't cost anything extra for customers who wanted to use it. It was managed securely from the account control panel. There was a selection of classes of sites you could choose to block; you could selectively block "adult content" and "advertising" and a whole load of other stuff.

All done using industry standard hardware and open source software.

Do we think sensible people would be happy with something like that, rather than forcing ISPs to kowtow to BT Cleanfeed or other commercial equivalent?
