Are you certain that your own content filters aren't affecting the search results?
Just looked you up and found a lot of your art. I even searched only E and T art and ALL of your E and T rated art showed up in the search results.
Also, I'm pretty sure being a NSFW artist is not a problem here. Even the biggest NSFW artists here, even with thousands of followers and having a majority of their content rated as A, still have their E and T artwork show up in search results as long as you don't have anything in your settings that would block it.

I just typed in your name in the search box and got a reasonable amount of your works as a result.
