Similarly: I remember spending quite a lot of time exploring [National Capital Feenet](https://www.ncf.ca/en/)'s Gopher pages in an attempt to find a link-to-a-link-to-a-page that would let me make arbitrary telnet connections, thereby bypassing their efforts to ensure that their free dialup service was only used to access their own services, rather than, say, to play Nethack on a public server at tamu.edu (whose exact domain name I can, alas, no longer recall).
