Honestly, as someone that's been picking up OSRS again (and is actually now thinking about RS3 given all of the recent progress jagex is making on removing MTX in it!), I'd be good with that. I still like to play it myself without botting, so anything to move the bots somewhere else I think would be neat. PvP folk lose some easy kills but that's about it for impact on regular players honestly.

The problem is, the reason the bots exist now is to sell the account or farm gp. The only way this would work would be if that bot only world was gated off from the rest of the economy like special gamemode/league worlds, naturally destroying any reason most bot makers make bots. Your love of automating for sport puts you in the minority of botters sadly haha

Officially blessed OSRS private servers are on the roadmap IIRC... maybe there's a future for a bot-olympics in one of those?

The official private servers were paused recently. https://oldschool.runescape.wiki/w/Project_Zanaris
