How long to keep the bot on for?

[LiquidRopee1]

So, currently, I have the bot on for no more than 3 hours at a time taking 1-3 hour breaks throughout the entire 24 hour day. Would it be okay to keep it running 24/7 like this? Would I be caught? Trying to uprade walls at th12, and it's a big pain lol.
Also, I have a 30 day subscription, does it eat up the subscription time if clashfarmer is not launched?
