I don't think theres any evidence out there that points towards the direction of him being cleared from the cheating ban yet, and that email looks like Bleed asking them if Juicy can participate in any VCT tournament and Opal only replied to what they asked
You can't use s1mple as an example because his ban was imposed by ESL not Valve. While Juicy's ban was given directly by Riot when he was playing in VCT, the difference between cheating in a 3rd party tournament to the main circuit is day & night. Riot has a rule to follow, you can't just forgive & forget something like this just because he's a better player now
