[ibsule]

Summary

Enforce a daily cap on the number of messages a user can send in order to maintain fair usage of the platform and prevent abuse.

Details

• Define and document a daily message limit (e.g., configurable value)
• Prevent users from scheduling/sending more than this limit in a 24-hour period
• Notify users when they are approaching or exceeding the limit
• Design error handling/UI feedback for blocked sends
• Consider exceptions for premium/privileged users

Motivation

Protects system resources, improves user experience, and manages fair usage across all users.
