Its a little tricky to set up, but I'm currently sitting on 385 queued posts, which means I can take a break and let my contributing keep going on "autopilot" for a good while if I need to.
Maybe not something to get into configuring while you're busy, but fyi :D
The tool just makes turning what you find into a post really easy. You just throw danbooru/pixiv/image links at it, and it does the rest.
I made it mostly because when I go exploring on pixiv, I usually find dozens of images worth sharing, not just the one. If I shared them all right then, it'd be real spammy.
Queueing them up instead means they get posted over time :D
