RecipeManagerBot is the importer behind Platefolio, a recipe app. If you see it in your logs, a person asked Platefolio to import a recipe from your site.
RecipeManagerBot/1.0 (+https://platefolio.app/bot; user-initiated recipe import),
and never pretends to be a browser.
robots.txt rules written for all bots (User-agent: *) are aimed at crawlers,
and many of them exist to keep pages out of search results. RecipeManagerBot is not a
crawler: each fetch is a single page a person asked for, like a browser opening a link. So
it treats User-agent: * rules as advisory.
Rules that name RecipeManagerBot are always followed. To stop it fetching any page on your site, add this to your robots.txt:
User-agent: RecipeManagerBot
Disallow: /
You can also disallow only some paths, the same way as for any other bot. Your robots.txt is read fresh on every import, so a change takes effect right away.
