Not normal. But possible. You have to take care at some Parts of the Profile.
Big Mobs to Kill, like the Quest where you have to Kill Sha. If your Char is weak and Die there 50 times, i think looks strange for normal players, to report you.
And there are some other Parts, fighting all time again respawning mobs, endless. Looks strange too.
So there are enough Parts while Questing to do a Report if someone see this kind of situation.
At Classic and other Addons, there are a lot of Grinding steps. I always see there a lot of other People doing the same like my Toons (Grinding).
So be careful while Questing. Get Hands on "LogMeOut" and set it sensitiv. better log out and waste the time before you got banned.
And again, the Community needs a combination of LogMeOut and Arelog/Hbrelog, for a better configuration of Waittimers till a Relog starts... and a lot of other options.
