Please take note that you're in the risk of being banned just by using a 3rd party program. I hope you know that the second you started to use one.
Servers doesn't matter, Low Pop = Less DCs and High Pop = More DCs depends on your internet tho.
This might actually help you, assume that you are just farming and hate being bothered.
I don't bot 24/7, but close enough tho, most players sleep whilst botting, but I'm the opposite, I don't bot whilst sleeping, I guess I could say that I'm 15/7 botting.
Here are some few tips to not get banned:
Try to make your own bot or modify bots that you find here in MPGH, change Pads of bots so that you'll look less obvious, it would really be stupid if you just popped up in the middle of the map suddenly, and that would be suspicious thus might get higher chance of being banned.
Also avoid opening up shops that are suspicious, some might be noob trap or I honestly have no idea if there are still shops that are noob trap.
Adjust bot delays, delays should vary depending on your internet connection.
