gollark: dnscrypt-proxy, don't know how anonymized it is.
gollark: Yes, I also have that.
gollark: Some osmarks.net services have basic auth despite having their own authentication mechanisms because it doesn't really cause any problems and I don't entirely trust said own authentication mechanisms.
gollark: I have TLS because it massively reduces the chances of highly important* data going to osmarks.net being intercepted, even though it doesn't obscure *everything* and has holes.
gollark: You can use things because they will probably increase security. Even if they are not perfect.
