OSRS came to be after years of updates and changes to RS3 which slowly alienated the original base. Now, what was originally a reboot of a 2007 backup of the source has hugely eclipsed the original in popularity. Pretty great story.
There are also straight up bots people use sometimes in pvp which aren't possible for any human to fight. They can react to what you do instantly and perfectly, you can't really touch them. They're very rare though, the people who are capable of making them keep them expensive and uncommon.
For people who don't play the game it might be hard to understand the scale of the botting problem. Recently the majority of the top 100 accounts in the highscores for killing a boss called leviathan got banned. Its not unlikely that in the top 100 there was one real human (who went fron rank 77 to rank 14 in the highscores because so many who were ahead of him got deleted).
