|Description:||Many sites offer secure connections through HTTPS. For a site such as this one which carries a lot of content employers, universities, prudish governments, snooping neighbors, and other prying eyes may not want people to see, it makes since that an option for this would be available.|
I don't necessarily think this should be required such as through HSTS, but rather something which a user can manually type in, enable through an account preference, or use automatically with a browser tool like HTTPS Everywhere.
I personally really would like to see HTTPS available on Gelbooru. If doing so would need payments through Patreon in order to be possible, I am willing to contribute if you send me a private message.
