[Feature request] Retain cached artists in the favorites tab.

[eskeletor97]

Sometimes artists will remove their account or get banned leaving a blank.

It would be cool if the app displayed what account it was and used the cached image if it's available, but mark it with a red outline or something similar to indicate that it's gone. It's hard to keep track of who it was because I follow like 400 artists.

Check your follow list, then find the one that has no illustrations posted, and then unfollow it (note that if you unfollow it in the list, the button will not load after you click on the homepage) I just got stuck on this problem.
