Could be great links to share over Riot Games streams.

• MasterCard has asked Riot to keep an eye out for negative sentiments on official Riot streams
• Riot has asked esports content creators working with official Riot properties to watch out for any negative sentiments toward MasterCard
• Moderators have been told to look out for any unusual activity around the MasterCard issue

No better publicity than getting their own efforts thrown back at their faces.

MasterCard is running an effective PR campaign against themselves. They can't stop giving their critics all this gold.
