Hiding 'Categories' seo/meta link?

Maybe this can help you:

Needing to edit robots.txt file - where is it?

PR was just merged: https://github.com/discourse/discourse/commit/6515ff19e5c8e62ba3aaecb5947eaccdcbbaf0dd If you update to latest tests-passed, you’ll be able to customize robots.txt at /admin/customize/robots. The page is not linked to from anywhere in the UI, you’ll have to copy and paste the URL manually into your browser. Note: if you override the file, any later changes to the site settings that modify robots.txt (e.g. whitelisted crawler user agents etc.) won’t apply to the file…

Where you yourself can set the rules for categories.
