Here is a video of him running on the 2012 olympics: https://www.youtube.com/watch?v=vB_g-RSIGfM
He was so much quicker than everyone else on the paralympics, it wasn't a challenge for him. By comparison the same 400m para final also in 2012: https://www.youtube.com/watch?v=qn4FWEm4FzM
I don't like this kind of community/user instance because 2 instances have to deal with the same problem. E.g. a rogue user can troll on most community instances until they are banned by their user instance.
The instance fragmentatios is not as big issue as it's quite easy to create new accounts. There was a thread about this some days ago here, I also use different accounts on different instances for different topics.
