With Midrub you can publish in any public Facebook page. Nevermind if you have liked or no it. But you must be very careful because if you want to spam a page(Someone says: No, i want only share a link no spam) you may be with a click banned by the page’s administrator or he can report your Facebook application and you will lost your Facebook application.
You can use this feature only if you are sure, you’re posts will be consider “not spam” by the page’s administrators. The page’s administrator will see the name of your Facebook application in each your published post.
The autopost’s class can be provided on request.
