4# Retired paths that now return 404/410 (/images/, /user/, /loginbox) are intentionally

What do the bots actually get?

This page reads robots.txt, which states what photobucket.com asks of crawlers. A firewall or CDN can still refuse a bot that robots.txt allows. The live check requests the page as each bot and shows the status it gets.
