Kubik from polish team noMERCY also got vac banned around the same time emilio got banned,but he got unbanned soon after
hopefully it's the same case for emilio,also note this was an online tournament not lan 
Why do they only unban pro players? Tons of players got VACed by mistake and they don't get unbanned.. As Valve said "The ban cant be lifted".
Only few might get unbanned and they come from overwatch bans. Lot of people reporting every day people that don't hack.
On the other hand is bans what's don't come from overwatch. Most of them are 3 party programs or scripts and them are real, you shouldn't mess programs that mods your game or give you advantage.
Tons of players banned mistake, I don't believe it. They always had something

Cly example admitted he was hacking.
