In testing the Image Recommendation API, we noticed that this placeholder image (https://commons.wikimedia.org/wiki/File:Missing_Arachnida.png) was recommended for many articles in cebwiki, likely because it is used often in itwiki for articles with no images.
The algorithm attempts to filter those out, so this task is meant for us to check on why this image is not filtered out. We may be able to discover some improvement.
