There's very few methods in the game that can make 800k/hour.
300k/hour should be a realistic goal.
10 accounts at 300k/hour is over $60 a day doing nothing.
They can see if you're on ficiall or 3rd party.
They can also see time played.
Both of these are detected even if you're not botting. They can see you're using Osbuddy and played 10 hours daily.
What?
Servers, proxies, accounts, bonds
small could be 10 bots or 50 bots or 2 bots.
Could be $5 if you only need a few bonds or $200+ if you're buying servers and lots of bonds.
