So, I just reviewed the demo and it does look like a spinbot. However it could also be someone who just spams his mouse around, and suggesting next time to also spectate from a thirdperson view which may result in a more clear outcome.
As for now, I'm thinking this is the use of a spinbot and not towards someone spamming their mouse around as it's way too smooth in a pattern.
*EDIT* I forgot about the first demo as
@Lucas had issues reviewing it himself. Watched it and it's definitely a spinbot as he's navigating just fine.
Banning him permanently.
