Depending on the settings, google docs won't be visible without google account. At least now yours won't be visible without logging into google services.
For sake of simple and free of charge ways of posting content, I would encourage to take some sort of blog service. Blogspot? Tumblr? At least latter one became same sort of nuisance as social media. Erasing any posts where even modest nudity or "extremes" is found. Making it quite risky to use for industrial-noise posts with such material. If there is no such material, then those free blogs could be good alternative.
Those platforms would be better and easier to visit, navigate and search content, than posting file into google docs.
