I was using the nmz bot almost a year ago and never got banned I stopped half way through. I want to finish maxing my Combat. Is the ban rate relitvily the same since last year on the nmz scripts is it still low ban rates or have it gone up? 
 

I was using mirror mode only.

I dont think anyone has any actual hard data to say its 1 in 10 or 1 in 100. All rule breaking comes with risk of getting banned. There are so many variables so I suggest not risking any account you do not wish to lose. With that being said, I find nmz to be relatively low ban rate but as i said with so many variables like run time, activity level of the bot during the activity (afk or click intensive), breaks, player reports, client/bot bugs causing undesired behaviour and most importantly how YOU use the bot.

I do not think I have had a single ban from sand crabs to base 90 melee stats in nmz but I go to great lengths to disguise myself in plain sight. 

 

TLDR; not a soul could say. High? Low? depends on usage.
