I don't think of this one as actually fake, just mislabeled. When I watched the original video, I didn't think that she was blind, especially when she did the twizzles. How could a blind person do so many revolutions and come out facing in the correct direction? Also, it seemed to me like she was in and out of the "blind" character. And she was just too good technically.
I had to keep clicking to get more comments before I found the one that gave the skaters names. Once you have that, you Google them and find other performances by the same skaters. It took a lot of clicking but not really much time; I found it in about 5 minutes.
I don't think anyone set out to make a fake here. Someone saw the video of the performance, incorrectly thought that she was blind rather than portraying a blind person, and re-posted it with an incorrect description. Other people accepted and re-posted it without questioning it. I was lucky that someone actually did a comment on that particular re-post to correct the narrative, and that they gave the skaters' names.
