How to completely stop atop from creating logs for good?

I've installed atop on a orangePi/RaspberryPi with only 40MB for /var/log. It quickly filled my partition to 100%, I then purged it apt purge atop to remove it and its configuration files. * atop binary doesn't exist * its file in /etc/init.d doesn't exist * no systemd service called atop Nevertheless, after a reboot, the /var/log/atop folder comes back full with the old atop files. * **How can I completely remove it for good?** Edit:

$ ls /var/log/atop/
atop_20200822  atop_20200826  atop_20200830  atop_20200903  atop_20200907  atop_20200911  atop_20200915  atop_20200919
atop_20200823  atop_20200827  atop_20200831  atop_20200904  atop_20200908  atop_20200912  atop_20200916  atop_20200920
atop_20200824  atop_20200828  atop_20200901  atop_20200905  atop_20200909  atop_20200913  atop_20200917  atop_20200921
atop_20200825  atop_20200829  atop_20200902  atop_20200906  atop_20200910  atop_20200914  atop_20200918  atop_20200922

I removed atop on 2020/09/22, the last file. And it regenerates the same folder with the same files again and again after each reboot. ### atop folders and files:
