Isitsafe?

Good Evening warmane people ,Hope You're doing good
So i was watching addons guides on youtube and a guy maked a good guide with a link of a rar folder full of addons he uses
i wanted to dowload this folder and use it but what if this folder contain something that may get me banned ?
so my question is :
is there somekind of addons that are considered as bots or something like that because when i play i always see this red messages
SOMEON***** Has been permanently banned for using bots
and if there is such a thing is there a list of forbidden addons
Thank you and sorry for being Newbie i have always wanted to play wow but i always finish by deleting my characters and deleting game so i've never learned playing properly
