I noticed in my notifications that a bot has liked several posts of mine over at the Atom discourse. Not only are they displayed in my notifications even after they were removed due to a ban (probably), which is rather annoying, they do not disappear from the forum list.
Try clicking on this post’s “1 person liked this” link. Nothing happens.
Now, try clicking on this post’s “2 persons liked this” link. Only one avatar is displayed.
