Hello,

1. Ensure that the discussions on EasyDiscuss have a language assigned correctly, Persian or English. If not they will be listed everywhere, if EasyDiscuss doesn't support a language to be assigned to a post discussion obviously you can't differentiate by language.

2. Use exclusions to remove certain category, articles or links from a sitemap. Content data source has exclusions dropdown, also Metainfo dashboard has exclusion link by link.
