Skips blacklisted posts in Next/Prev navigation and returns you to your post after logging in.
When browsing posts on e621 and using the Next/Prev navigation, blacklisted posts are normally still visited — just shown with a "blacklisted" banner instead of the actual content. This script eliminates that annoyance by automatically checking ahead before you navigate and skipping any blacklisted posts entirely, taking you straight to the nearest clean one in either direction.
Your blacklist is read directly from your e621 account, so it stays in sync automatically with no manual configuration needed. All blacklist features are supported, including multi-tag entries, negative tags, and conditional entries. The calculation takes a second or two, so don't be worried if it doesn't work if you click on to the next post too quickly.
Requires a logged-in e621 account and Tampermonkey. Works on any Chromium-based browser.
