I think the reason why Spiral Knights doesn’t have bots (even back when I joined in 2013, iirc there were no bots) would be because there’s really nothing to gain from it. Maybe selling accounts is all the RWT you can get in that game as if you just want orbs of alchemy (for example) you either farm for them or you pay real money to get energy and buy them in the Depot so there’s no need for a useless middleman such as a bot of any sort.
Paying for a bot to farm stuff for you would be a waste when you can get them directly. There’s also the aspect that you can trade Crowns for Energy, so you can also farm for drops while getting Crowns to convert to energy and buy stuff, essentially getting drops & buying from depot which is a lot more efficient.
There’s also no duping I’m pretty sure, so you can’t have stacked accounts hand out materials in bulk for affordable prices.
