Lately I don't use it that much, I have a script to get images from my favorite accounts, but I keep using the same filename format out of habit. Even when I download a pic directly, I often add the artist's name like this myself.
To save you the hassle of investigating, I can tell you that, as retarded as it sounds, it's impossible to get a tweet out of the image filename, so sadly you can't do something like with Pixiv.
