Samuel is from the US, he has never talked to Leha, doesn't even know his real life name - so i didn't get why you called Leha Samuel's friend 
Sven vs Zhura, Yoakim's skatw, Aasheim's kalatw, badly executed tricks etc - he was always right - and truth is: there is way better to have a forum member like that - than an ass licking kid with 256 karma, who will be nice to you all the time and give shitty tips - just for the hell of it
i d rather have somebody to tell me where i am wrong and what can be improved 
and Leha is not the only person on bf who had low karma and was disliked but in fact was contributing a lot to the community
DantheMan also had -200 karma and people were pissed at him for some of his jokes and comments - however he organized Amsterdam meet, was a judge at rbss, and deserves recognition for that
same with Leha, he used to have a lot of haters both on bf and in Russia too - now he is probably the most respected and influential person in Russian freestyle
You just missed the point.
Do you realize that some people went into freestyle just for the fun of it, and not to improve so drastically while having no fun at all?
Why should freestyle be about improvements all the time? Like Linde said: "Freestyle is way more than just showing off skills, and being the best,
it's about friendship, and it's about having fun."
The way Leha and his posts on here, I've never seen him making an effort to tell anyone what his trick is clean (I think he never went into any other people's videos besides the one that he posted on telling people to improve their style and starting huge arguments (sometimes up to 7 pages you kidding me?))
Do you know how some of the beginners would feel like having him on their asses telling them to improve their style over and over again, without actually giving them tips on how to improve?
On this life, there are things way higher than just being good at freestyle. Now I ask you: do you guys seriously want to make livings out of freestyle in the future? If no, then why should you even care about criticizing people, while you can be friends with them? If yes, you will have to travel the world one day, meeting new people, and the way you act will not impress them. Either way, you just have to learn to be compassionate and forgiving towards other people, in order to achieve the true happiness that freestyle brings.
Now I'll tell you a story:
- Once I was a little boy in Vietnam. And in Vietnam, everyone was very strict, especially teachers. If I did something wrong, even just a little, they reprimanded me, telling me that by the way I'm going, I'll never achieve something in life.
- When I came to the United States, I recognized the teachers were so open minded. They didn't try to harass me each time I'm doing something wrong, but encourage me to try and fix it myself, with encouragements and promises of a better future.
- And that's why I've improved significantly, in both my mind capabilities and my attitude towards other people, especially my professors. Now they are not powerful angry deities about to strike me every time I'm wrong, but rather understanding and compassionate friends who I can count on every time I run into trouble.
- That is how I improved, not by insults and rude tips, but by passion and love.
Do you understand why Jesus or the Buddha, or Confucious were loved so much by the people? They educated people, but they did so in a compassionate and loving way. But they have all made tremendous amounts of contributions to the world. That's the ultimate proof that you can change the world while being nice. And if they can do that, why can't you?
