Depends, I'm not a big gold farmer, but if you have good methods that work well, you can easily make a lot with very low ban rates. If you know anyone who can scripts or if you can scripts (this is the one I recommend) - then you can find a method and make LOTS of money off of it. It's especially good with low maintenance since OSBot's randoms are pretty reliable (still some fail occasionally). TL;DR - If you got good methods, go for it. If not, you'll be dealing with a lot of bans
edit:
It's annoying if your accounts are constantly being banned, so I guess it's not worth it if you're going to be constantly doing randoms, xfering stuff, and making new accounts from banned ones.
