s1mple also cheated in CS 1.6 but he was lucky that CS GO was released and he got his second chance by this. He has a pure talent now though.
He was always good but also too driven and done a few stupid things along the way. s1mple has actually cheated and been detected in csgo but not by VAC only ESL wire client I think it was. They dont ban forever luckily as ESL is a big name and none of the other providers duplicated the ban including Valve and nobody else detected him cheating that I read about. So s1mple got an ESL ban played outside of that for a while, he also tried to evade the esl ban with other accounts and was rewarded with an extended ban term again purely for ESL.
I think it was 2 or 3 years while he was quite young, he teamed up with Hiko while serving the ban in other LAN and then even before the ban expired Hiko had him drafted into Liquid on the other side of the world When ban expired he could goto the major as normal, very lucky he didnt end up life banned. Obviously we know the Liquid thing was volatile but it made a great story, I think s1mple has advanced to give more respect since those days.
Rules changed recently, I believe under 18 even if VAC gets a players account banned they may later be let off with expiry, I dont have the detail but might be after 5 years. I think iBP should have been let off after 5 years because one person on that team wasnt even 18 at the time and was dragged into the mess but Valve seems no upside to appearing to be a soft touch I guess. Tons more money in CSGO now, it should be quite minor for any regular league I read the pacific region suffers problems but I miss most of those games.
I have personally played vs pro players who cheat (not recent), the demo was a joke but they were not detected by ESEA or valve etc. A observer or those guys who manage or view players at LAN, they had to do it manually and then other org declined them. Years later they did detect him (a few months past my having him in my game demo/matches) but he was already banished in effect, s1mple was super lucky
