why /var/spool/abrt/ folders not deleted

we try to delete all abrt folders as the following ( on redhat Linux machines ) find /var/spool/abrt/* -type d -exec abrt-cli rm '{}' \; rm '/var/spool/abrt/ccpp-2018-09-03-14:52:11-5653' rm '/var/spool/abrt/ccpp-2019-03-26-12:18:52-31410' rm '/var/spool/abrt/ccpp-2019-04-07-05:50:25-16907' rm '/var/spool/abrt/ccpp-2019-10-29-14:20:46-20059' pwd /var/spool/abrt but we still see the folders and folder content as ls -ltr /var/spool/abrt total 24 -rw------- 1 root root 70 Nov 5 09:43 last-ccpp -rw-------. 1 root root 48 Dec 9 03:25 last-via-server drwx------ 2 root root 4096 Dec 9 18:45 ccpp-2018-09-03-14:52:11-5653 drwx------ 2 root root 4096 Dec 9 18:45 ccpp-2019-03-26-12:18:52-31410 drwx------ 2 root root 4096 Dec 9 18:45 ccpp-2019-04-07-05:50:25-16907 drwx------ 2 root root 4096 Dec 9 18:45 ccpp-2019-10-29-14:20:46-20059 why abrt-cli rm not removed the folders? from abrt.conf grep -v "^#" /etc/abrt/abrt.conf MaxCrashReportsSize = 1000 DeleteUploaded = no AutoreportingEvent = report_uReport AutoreportingEnabled = no PrivateReports = yes
