KT might sue online user for defamation of Flash?

The details are really fuzzy right now, but if I'm correct, a guy who goes by the username "잡담" on "스갤"(an anonymous Korean BW forum, which is part of the site DC) may be sued.

The KT Coach LJH was notified by KT fans tweeting him about a guy who consistently posted malicious comments about Flash. A twitter conversation ensued between 잡담 and LJH.

Either I haven't discovered the function yet or twitter is retarded, so I can't see the conversation as it folded but just see the two sides tweeting.

I saw the mention earlier.. Looking at what you've written up to now... starting from unspeakable words... You went too far. I don't get what crime Flash and the other progamers have committed towards you to cause you to act like this.
I felt that the malicious comments were severe these days, but I didn't know it was this bad. I acknowledge that a part of the comments on 스갤 and Fomos are for fun, but this is just focusing on and attacking Flash.
This is an clear act of defamation towards the KT sports team and Flash. As you can see from my twitter ID, I'm using it as an unofficial team twitter, and our sports team is also monitoring it.
I almost weakened when you started mentioning your parents. I'm close with Flash's mother. She also checks a lot of online communities. Do you think she didn't see what you wrote? Do you only worry about what your parents think and not what other parents' think?
This isn't a laughing matter and it's beyond my hands. I've passed on the material that the fans have given me to the KT front and will concentrate on the SKT match.

And 잡담:
(not translating all of it, but just the general gist)
- is a Bisu fan
- posted saying that Bisu might be better than Flash and got flamed for it by Flash fans -> caused him to start insulting Flash as payback
- never insulted him elsewhere
- didn't mean for Flash or anyone else related to see it
- says that the guy who reported him is being two-faced since he also has insulted Bisu (notably PSing Bisu with a picture of a monkey with an enlarged nose)
- only insulted Flash because of all the Flash-haters
- begs not to tell his parents who will be disappointed by him again
- says that he'll take the punishment, and learn from the experience
- but then the next day, begs to be let off

Ugh.. it's basically =_= really ... 비굴해.. the way the guy's begging.

According to rumors, KT wants to sue, but Flash is against it. Supposedly he said that although he was hurt by the comments, 잡담 is still a fan of esports and should be let off. Not sure about this.

(There's already a webcomic about the situation.
I'm sure someone else *coughstartswithanmcough* will translate it because I have my last exam tomorrow and really should be studying.)

I don't really know how bad the comments were, but considering that 스갤 is normally a really bad-mannered place(the average post on it is probably worse than any post that's been posted on TL, including the banned ones), it's got to be pretty bad for him to be singled out. I haven't found the posts, and I think the original posts were all erased.
Heard that it had to do with attacking his personality, appearance, and parents.

Although I'm not sure if KT will actually follow through, especially since Flash apparently wants to let him off, I know that people have been sued before on DC.

-edit- looked up a few previous cases, and apparently on 스갤,
- a guy in 2005 was about to sued for pretending to be other users and flaming players, but he
committed suicide before the suit (the suing occurred after the suicide, not before. the owner of DC sued him only to find out that he was already dead)
- a guy posted that he was going to kidnap, rape and kill [B_Blade]Leader's daughter(probably not for real, but just to state how much he hated him), he read it, obviously got pissed off, and took legal action
