I suggest you to wait till the new Ref system is online, also almost all ref bots cost you 500 MB of ram per client, so its all depends on your harwere like btm1337 said, and for the account creator, all u need is to have an account on deathbycaptcha, the registration is free but u need to buy credits for the captchas u can read it on the site, and here is a link of working free to download account creator.
V1 FREE and
V2 PAID.
As i know, around 5-7 hours to get from level 1 to level 10 with exp boost.
