- TS believes MagicAmy is one person and is actually Hyerim Lee
- They investigated the accusations extensively and determined there was no case of fraud in regards to her interactions with TS, but the matter was still a major personal issue between her and those accusing her
- No proof found for win trading/botting/account sharing allegations
- TempoStorm offered to support MagicAmy to have her play in an offline tournament to clear her rep but she chose to leave the scene instead.
So basically, TS investigation concluded that MagicAmy was in fact not a scammer, but she chose to leave anyway.
