I have added facebook comments plugin to my site, and I want to control comments in the site. Is there a way to give certain facebook accounts the privilege to delete comments from the comment box?
it's fairly simple. All you need to do is to add an app id meta in your page head:
<meta property="fb:app_id" content="<?= APP_ID; ?>" />
Then, every people listed as Developper in your app roles settings can moderate comments in comments boxes.
Some weeks ago, there was a Moderator roles available, but it's now deleted. Not sure what this particular role became; but Developper and Admin can moderate comments.
