What problem are you trying to solve?
You can limit resources, number of user processes, or file quotas, but these can prevent users from doing valid tasks.
Plus if someone executes a shell script, it may actually run lots of commands every few seconds, and be completely legitimate.

EDQUOTA(8) System Manager's Manual EDQUOTA(8)
NAME
edquota - edit user quotas
SYNOPSIS
edquota [ -p proto-user ] users...
DESCRIPTION
Edquota is a quota editor. One or more users may be specified on the command line. For each user a temporary file is created with an
ASCII representation of the current disc quotas for that user and an editor is then invoked on the file. The quotas may then be modified,
new quotas added, etc. Upon leaving the editor, edquota reads the temporary file and modifies the binary quota files to reflect the
changes made.
If the -p option is specified, edquota will duplicate the quotas of the prototypical user specified for each user specified. This is the
normal mechanism used to initialize quotas for groups of users.
The editor invoked is vi(1) unless the environment variable EDITOR specifies otherwise.
Only the super-user may edit quotas.
FILES
quotas at the root of each file system with quotas
/etc/fstab to find file system names and locations
SEE ALSO
quota(1), quota(2), quotacheck(8), quotaon(8), repquota(8)
DIAGNOSTICS
Various messages about inaccessible files; self-explanatory.
BUGS
The format of the temporary file is inscrutable.
