I am of the view having a .gopher and .onion version of sites is important for avoiding government blocking where possible and to keep information as free as possible.
can you recommend some gopher server that is actively maintained? I always wanted to host gopher site but could not find a strong solution that I will not be afraid to be easily compromised.
I don't know the answer, but fortunately the protocol is so simple that you have the option to write a short Python script.
What do you mean by .gopher? Gopher is a transport protocol like http and can work over tor or any other transport just fine.
