Worked for quite some time at Southern Master Farmer at the Farming Guild, but at one stage it broke and continued to try to go to the Northern Farmer, which made it very obvious that it was a bot.
This was caught on by a few people so it's not unlikely to receive a ban for this error.
The log is as follows:
02:50:22 DEBUG User has resumed bot.
02:50:24 INFO Running to the master farmers.
02:50:34 DEBUG Resetting master farmer target. --> I imagine this is where it went wrong
02:50:34 INFO Pickpocketing farmer.

It pretty much offers the most versatility you'll see, with an option to "auto-configure" if you prefer not to specify every little detail.
