I've only ever been banned once, and it was a 3hr afk report ban from BGs (bot was glitching out and just standing at start) but that ban was over 6months ago.
Since then i've leveled multiple characters (3 so far) to 90, used a grinding profile 85-90 for about 12-15hrs a day every day until 90 (same profile too 85-90).
Now i've just been using lazy raider for raids and using the daily profiles for rep gains on my main.
Monitor my daily bot about 50% of the time, and while leveling/grinding i check on it every 3-4 hours by remoting into my PC.
Never whispered, never GM teleported (that i know of), never temp banned, never banned.
