From time to time our website loses as lot of likes for example two days ago the number of like was more than 1k then all of a sudden it became 480
Also strange is that this query https://api.facebook.com/method/fql.query?query=SELECT%20url,%20normalized_url,%20share_count,%20like_count,%20comment_count,%20total_count,commentsbox_count,%20comments_fbid,%20click_count%20FROM%20link_stat%20WHERE%20url=%22printdirect.ru/index.php%22
Has 480 total_count
But this link http://graph.facebook.com/http://printdirect.ru/index.php returns "shares": 1912
What can be the reason of such a loss?
