Hello @arturamirov,
Thanks for reaching out.
The WordPress- plugin Blog2Social is a tool which shares your blog posts in your social media. You can delete posts in your social media networks manually only. If you delete the Blog2Social app in your Facebook-business integrations then Facebook will then ask you if you wish to “Delete posts, videos or events Blog2Social posted on your timeline.” when removing the app from your settings?” Did you proceed like this?
