I regret to say the Proxomitron web filter is well and truly dead. Unfortunately, while attending a "save the hedgehog" rally, it was fatally mauled by a jealous flock of rampaging echidnas.
For anyone interested in poking around the remains, the final version still works and may be available at independent sites like these...
In addition you may want to try these other web filtering programs...
P.S. Sorry about the ads here, but this is GeoCities page after all. Of course those using Proxomitron may not see them. :-)
P.P.S. I'm keeping the support AT proxomitron DOT cjb DOT net email address alive for anyone who really needs to contact me, but please understand I'm no longer supporting the program. If you're having trouble with Proxomitron or have questions about using it, there are several message boards that can probably help you out. For details, just check some of the sites listed above.
