I just noticed this, is this a bug?
When somebody in the feed watches an episode of Blue Exorcist Season 2 the picture is this one...
But when I go to the anime page on Kitsu, the picture is a different one (the more recent one that is also used by MAL)
Also, have you thought about maybe making the pictures on anime pages a little larger? Since they are right now smaller than on MAL and they tend to end up looking really blurry.
