Not just Kanavi's transfer, but it is very possible that there is another transfer that was also illegal (Plex's transfer). This has not been confirmed yet, but it is on the investigation. https://gall.dcinside.com/mgallery/board/view/?id=griffinlol&no=63169&exception_mode=recommend&page=1
The manager of Griffin, Cho, was accused for committing a default. http://www.inven.co.kr/webzine/news/?news=228795
cvMax said he could reveal more, but it won't be necessary since the investigation is going well.
cvMax also commented on Sword's behavior later on, after Griffin lost to IG. Original: "난 이 xx가 사람 xx로 안보여" Direct translation: "I can't see this bastxxd as a fxxking human" https://clips.twitch.tv/EphemeralNastySheepBlargNaut
Still-8, the company that owns Griffin said they will remove Cho and anyone related to the incident if their crime was proven to be true. However, according to Fissure, a former Overwatch professional gamer who used to play for Kongdoo Panthera (owned by Still-8), it is not just Griffin, but the company, Still-8 also has many problems. For example, they didn't tell him whether he received any offers from other teams (in fact he received several), and talked behind his back like, "this bastxxrd didn't even get any offer." He said there's more, but he doesn't want to say it since it might stir up the community. https://www.fmkorea.com/best/2319515266
Many of the Korean E-sports personals commented that those are prolonged corrupted practices. Not just Griffin, but it is very possible that other teams are doing it as well. They argued that there must be a stronger regulation and overseeing to prevent those from happening. The incident also captured not just public's eyes, but also the government's. Currently, there is a bill that is currently on pending in the South Korean Congress that addresses this issue.
Also, there was an anonymous report by someone who's a part of the investigation team. They said what we know now may be just a tip of the iceberg. (I remember reading this, but couldn't find the link. Also, this one could be just a rumor).
