If you don't want to get banned....

Agreed, it seems to be common sense.

#1. Use the plugin "avoid players" set to 200 yards. Yes you will definitely skip some nodes but you will never get reported as you just fly on by.
#2. Be random. I gather for 1-3 hours a day at totally random times and different zones.
#3. Set plugin "logmeout" for a random time each day. 1hr 38 mins, next day 2hrs 12 min.

You wont get rich quick but you will be richer than if you were banned.
