Kice is still a GM level player, I've seen him play in person, but he's definitely not good enough to be taking games off the best, that much we know. Now, if we take what Seo has said himself, that he doesn't do coaching, and we know his english is horribly broken, we put two and two together and can assume it was Kice coaching, this can be further proved by his students.
Now, Kice obviously got a bit of business through being a TGM (Whether or not he was recognised as a coach legitimately or not, I'm not questioning) but he also got a lot of business through word and mouth, evidence his coaching was obviously beneficial to people who sought after it.
Sure he may have achieved his TGM title through smurfs on his account, but you can't deny customers were satisfied with his coaching, they paid money, and they received a beneficial and worthwhile service, so it seems illogical that he is made to pay back the money he received from coaching.
