Hey man,
It's very hard to answer your question because it really depends on a lot of things. From my experience most of bans I got was from the other players reports (if not all of them). To decrease a chance that someone will report you try to follow this steps:
1) Find or create a good Fight Class for yourself
2) Same for the profiles you are using, quality matters here
3) Some plugins are very helpful, others are not. You need to really understand what they are doing before enabling them in too much numbers
4) It's important to take a look at bot security tab in your options (example: if you are using a gatherer product you can set to avoid other players in 300yd range. In many cases it will prevent you from meeting other players near the nodes which means less PvP and ganking.
5) Maybe this will be controversial but you need to at least keep your one eye on your bot (especially in the beginnings)
6) To test stuff you can set your own private server so you dont need to be stressed while waiting for your results.

Be sure that there are a lot more factors more or less important. It's just my tips.
Remember that even most careful and paying attention person can be and will be banned sooner or later. You can't eliminate the risk in 100% but you can greatly decrease it.
