I have taken these " free gem " surveys to many times and never received anything except tons of spam mail and waste of my time , I love this game and have spent a few hundred dollars on coc and really wish this could be fixed cause as of now I am an unhappy user...
Those are not official SC survey's, just spam. Staff do their best to delete spam from the clash FB page, but some inevitably slips through the cracks.
free gems on facebook ?
