Well, it has been a while but Riot has finally taken action against "reserving" account names.
Whether you’ve recently signed up to play League of Legends or you are a veteran player and you’ve tried to purchase a name change, you may have needed an extremely active imagination to register a summoner name on your first try. We know how frustrating it can be unable to secure your preferred nickname, and we want to help!
It’s come to our attention that there are a great many names out there that belong to summoners that have yet to log in and play a matchmade game. So, in response to player feedback, we’d like to free up these inactive summoner names so that they’re available for players that are ready to use them immediately.
So, if you had previously claimed a summoner name and would like to keep it, all you have to do is log in and play at least one matchmade game before midnight on Sunday the 30th of October. If you haven’t managed to make a showing of ownership by then, we will free up the name for those who are either just now registering or those would like to change their name.
If you have registered an account that is in danger of losing its summoner name, you will receive an email notifying you of your responsibility to log in and play a matchmade game in the next few days. Once you have played at least one matchmade game on your account, the summoner name in question will be yours to keep.
If you have already played your matchmade game at the time you receive your email, don’t worry! We’re still keeping track of your games; it just takes some time to send that many emails!
We’re looking forward to seeing you in game!
