Good proxies from @ProxyFish.
You add the proxy into the client then you can bot some-what safetly with your private IP.
I wouldn't suggest botting more than 2 accounts per IP.
RS3 botted accounts hardly get banned especially using colour bots. There are maxed mains and completionist accs still not banned after botting 1yr+ ect
I mean you could bot the RS3 stats easily, I botted max combat in 2 weeks and still no bans.
You could try to raise the price and bot it in the mean time but thats up to you.
