Hi Bro,
I just reading your case and I found that your ECAS is showing Decision Made. So there is no doubt about your file status and you can't find any result until you go through by any legal advisor and consultant who is registered CIC immigration consultant to deal with your case.
Re FB - Actually they don't check FB, but they like to mention name FB. Usually they check LinkedIn Profile and based on that they want to find out the applicant's professional working process and also linked with other colleagues or friends info that could help them to understand of applicant's professional outlook (at glance). In that case if anyone doesn't have linkedin profile then fine but if there is then should be updated match with documents provided with application.
Then question will arrived to many of you that how I know that they don't rely on FB because I don't have ID on FB and in GCMS note I found similar comments on Note-1. But my professional has matched with my documents in my linkedin and they have confirmed that they found FB match with my professional documents.
So check with your LinkedIn profile not FB and you will found that what was the variation.
In the bottom I am sorry for your case at the end of the day.
