Rate Limit for Replies

Problem:
We recently experienced more than 900 spammy replies from a single user within a day, creating a significant volume-management and moderation challenge. We would like a way to control how frequently individual users can create new topics or submit replies within a defined period.

Requested Feature:
Introduce configurable rate-limiting controls that allow community administrators to limit the number of posts or replies a user can submit within a specified time window.

Suggested Functionality:

• Allow administrators to define a maximum number of posts/replies per user within a configurable time period.
• Support separate limits for new topics and replies, or allow the same limit to apply to both.
• Example configuration: 1 post or reply per user every 10 minutes.
• Provide different rate limits based on user roles or permission groups, if supported.
• Display a clear message to users when they reach the limit, including when they will be able to post again.
• Allow administrators to temporarily increase, decrease, or disable the rate limit when needed.
• Ideally provide reporting or monitoring so administrators can identify users who are frequently hitting the rate limit.

Business/User Impact:
A configurable posting rate limit would help prevent sudden spikes in community activity, reduce spam and abusive posting behavior, and lessen the moderation burden on community teams. It would also provide administrators with a proactive control that can be used without having to ban users or entire regions.

Priority: High – The ability to limit posting frequency would provide an important safeguard against unusually high-volume activity while preserving legitimate community participation.
