pretty much title, like when was the last banwave? 

We've never been hit by ban wave. I personally have never been banned on retail using this bot and once in private server (just because i suicide botted literally 1 month without breaks in heavy population area) and I've been here since begining of this year

Hmm.. good to know thanks!

Likewise i've used this on retail for a very long time and never suffered a ban on either of my accounts

blizzard warden protection haven't "found" the bot.

So if you get banned, you have done something really stupid, like running the same profile as 500 others, or using the same fightclasses so everyone just "happen" to use every spell in a specific order all the time - or simply put the bot in areas where "real" players are running as well.

If you don't bot endlessly in a high pop area, then you're far less likely to be reported.

That being said, nothing is safe.  EVER.  

However, you can limit your exposure by being smart about your bot usage.

As people above have mentioned, avoid populated areas, and try to build your own profiles, if at all possible, or at the very least, your own fight classes.
