Due to G2A.com breaking Riot Games' guidelines by selling League of Legends accounts and offering 'boosting services' to players looking at a higher rank, they have now been banned from sponsoring any World Championship participants. Due to this fact, Riot has been asking teams to remove G2A.com logos instantly.
Complying with this request, large international gaming organisations including Cloud 9, CLG, H2k and paiN gaming have all removed their support for this ex-sponsor.
As announced and confirmed by The Daily Dot, Riot employee J. "Riot Sargonas" Eckert dealt the final blow. Eckert publicly stated that "This was NOT a decision we made lightly, and came after many weeks of back and fourth conversations with G2A to find a resolution, which we were not able to reach an agreement on. We do not at all enjoy affecting the income of the teams, but the LCS rules include guidelines specifically against this sort of thing. We did however keep teams in the loop during the process in an attempt to avoid any surprises."
