My take here was, I had not seen the media link on Twitter and saw the post directly on Anker community by one of the members.
If the survey was posted by @AnkerOfficial - that would have added authenticity that this was Anker’s Official Survey. However the first version was posted as a regular Survey (though this was by our friend @TechMan ) I wouldn’t put my details or even share it on Twitter / Instagram till the time I know this was Authentic by Anker / Ankerofficial.
I wouldn’t mind sharing my details to Anker - been doing it for so long for all the testing items 
But these forms are so easy to copy / remake, anyone can make duplicates and post it in pretext of Anker and harvest data which may be a bigger issue
