Is the IKON legit Riot partner or not?
I've noticed some well known streamers in the list and they promote to participate in their challenges, however, it requires installation of a desktop program in order to participate. The app has "Overwolf" in its name and I remember program with same name involved in many permanent bans for use of 3rd party software in the past. I couldn't google up any information if this is indeed legit Riot partner or Riot is not involved with them in any direct way.
Can anybody help?
