Adding a user to cron.deny will not stop/kill the running job for that user. Adding a user to cron.deny will only blocks that user from being able to use crontab command only.

from man crontab:

If the /etc/cron.allow file exists, then you must be listed (one user per line) therein in order to be allowed to use this command. If the /etc/cron.allow file does not exist but the /etc/cron.deny file does exist, then you must not be listed in the /etc/cron.deny file in order to use this command.

this command meaning at above is refer to crontab command itself.

Which brings up an interesting situation. If a user has existing crontab entries and is then added to cron.deny, the existing entries will continue to be run and cannot be deleted by the user. – doneal24 Dec 07 '20 at 21:34
@doneal24 usually user do not block itself, that's most probably a sysadmin that can also delete them – αғsнιη Dec 07 '20 at 22:29
