Except IMC is not an Argentinian company. Not even one based in South America.
The company is based in Korea, the game you’re playing published internationally. You’d be dealing with a cross-borders lawsuit. Good luck with that.
In the end, IMC would just redirect you to their server provider and those would blame the DDOSers and player overload and in the end you’d still lose a lot of money and gain nothing.
Edit: Also, by signing up you agreed to the EULA that includes the following paragraph:
“NEITHER IMC GAMES CO., LTD. OR ITS THIRD-PARTY PROVIDERS, NOR ANY PERSON OR ENTITY INVOLVED IN CREATING, PRODUCING OR DISTRIBUTING ANY CONTENT OR SERVICES CONTAINED IN THE GAME, NOR ANY OF THE IRRESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES OR AGENTS, MAKE ANY WARRANTY WHATSOEVER, INCLUDING, WITHOUT LIMITATION, THAT THE GAME WILL BE UNINTERRUPTED OR ERROR FREE; NOR DO THEY MAKE ANY WARRANTY AS TO THE RESULTS THAT MAY BE OBTAINED FROM USE OF THE GAME OR AS TO THE ACCURACY, RELIABILITY, QUALITY OR CONTENT OF ANY INFORMATION, SERVICE OR MERCHANDISE PROVIDED ON OR THROUGH THE GAME.”
and
“This EULA is governed by and construed in accordance with the laws of the Republic of Korea.”
Now, EULAs in some countries have ben appealed through lawsuits beforw, but you have to prove they’re actually illegal by the country’s laws
