SkyBlock
Detailed description of the idea (1 idea - 1 post)
Since new public islands are being filled up very quickly on the SkyBlock server, I think it would be possible to delete them after some time if players are not playing on their publicized island, and upon logging in, they could create it again if they play, because currently there are countless public islands, and players don't log in for months, I think there are too many of those public islands and it's difficult for players to find other people's islands when they need to.
