Gelbooru Image Bot for Misskey

Simple python bot which scrapes images from gelbooru based on specified tags every hour and posts to a misskey instance. The script can handle multiple bots simulatenously.

• Uses a systemd timer.
• Posts original source when available.
• Attempts to optimize downloaded images for size with PIL.
• Attempts to renote the original source if possible.
• Option for posting to hashtags (limits to once per day to avoid drowning out other content).
