Well, I'm gonna say a few words too. As a quite experienced awp player, it should be taken seriously. In english of course, that everyone could understand.
I watched a demo, 1/2 speed when L6 was getting kills. Maybe some of his actions may look fishy, but everyone who plays a lot of AWP servers will know some facts.
So lets begin, I'm going to point it out so it would be easier to read.
1. L6 is a very experienced player, he played for many hours generally cs, but mainly awp servers. That's why he know some spots, scans, timings, etc. When you are playng the same map for X times, you know it very deeply, so you know some walls you can shoot to get kills. I'm also like L6, trying my luck, shooting walls and waiting for some luck. For every experienced awp only servers player it should be obvious.
2. That scan on the ladder - you know that on this map you can spot a barrel of a player who is on the ladder. And sometimes it's just another spot to try some luck scanning
3. Timing - it consist of map knowledge and some luck, nothing suspicious
4. All other stuff seems normal to me, just good awp gameplay
5. To sum up, his gameplay is just: map knowledge, expercience, some luck and skill, nothing more
@Master.M I don't want to judge you too quickly, but your "ESL expert" doesn't seem to be legit. This screenshots could be easily faked and chat could be written by yourself. I think admins should not treat that seriously
Thank you for reading my opinion
Cheers
