@miran, someone uploads a video and it is posted here. then people comment saying they can definitely do this and others too so he needs to do better is what i meant 
Only Sam said he can do better and that was only when after Kersche's said that the people who don't like it can't do it. Sam's first comment was constructive criticism and generally good advice, but I guess it was too much for Kersche's ego to read anything apart from "great", "amazing" or "sick".
Overall there were only 4 "negative" comments and no one actually said anything bad about him or his uppers, so you're argument doesn't make sense to me.
P.S. If you want to improve, you need to listen to criticism as well, especially if it's coming from the right "source", not just comments like "sick", "amazing", etc. which will boost your ego, but won't provide you with any actual feedback.
