Hi, I’m also having the same issue. When someone posts a comment via the FBSEO plugin – it is also being published as a WordPress comment as well;

Surely it should be one OR the other?
Is there any way (other than disabling WP comments all together) to stop this duplicate commenting happening or will I have to use a different plugin?
