(It's embarrassing to post in badly machine translated japanese, but ive been on this site for a while now and the english speaking fan artists have figured this out and we have all greatly benefited from it!)

For artists struggling to find an audience: use the "alt text" on the image to enter the name of the character. The site uses "feeds" rather than an algorithm like Twitter, and including the character's name makes it easier for people to find you. If you want to increase your followers, this is how.
