Old League of Legends (LoL) accounts do not get deleted. The account content, such as champions, skins, and RP (Riot Points), will never be lost due to inactivity. However, there is one aspect that can be affected by inactivity, which is your Summoner Name.
Your Summoner Name is the unique name that identifies your account in the game. If you do not log in to your account for an extended period of time, there is a chance that your Summoner Name can be changed or even taken by someone else. This is because Riot Games, the company behind LoL, periodically frees up inactive Summoner Names to allow other players to use them.
The exact timeframe for when a Summoner Name becomes eligible for release is not publicly disclosed by Riot Games. However, it is generally believed to be around one year of inactivity. This means that if you have not logged into your account for a year or more, there is a possibility that your Summoner Name could be changed or taken by another player.
It is important to note that while your Summoner Name may be affected by inactivity, your account content remains intact. This means that even if your Summoner Name is changed or taken, you will still have all your champions, skins, and RP when you log back into your account.
In terms of gameplay progress, inactivity can have some consequences. If you do not play ranked games for a certain period of time, you may start to lose League Points (LP) and potentially even ranks. This is due to the nature of the ranked system, which aims to reflect your current skill level based on recent performance. If you are inactive for an extended period, your LP may decay or you may be demoted if your rank falls below the required threshold.
However, it is worth noting that LP decay and rank demotion due to inactivity typically only occur after a significant period of inactivity, such as several months. Regularly playing ranked games can help prevent these consequences.
To summarize, old LoL accounts do not get deleted due to inactivity. Your account content, including champions, skins, and RP, will always be preserved. However, your Summoner Name may be affected if you do not log in for an extended period of time, as it can be changed or taken by another player. In terms of gameplay progress, inactivity can result in LP decay and potential rank demotion in the ranked system, but this typically occurs after a significant period of inactivity.
