It’s in partnership whith Riot Games, I have to give 200+ game codes for Hextech Chest per day. If I need to whisper them to tell them to visit the site, I prefer whisper them to give them the codes directly : “Hi, these are your codes XXX-XXX-XXX Enjoy !”
The idea with an extension seems good but we prefer not to rely on extensions for that
If the limit of 40 accounts per day is true even when you answer a whisper initiated by a real person, it is somehow problematic
