Users can report content and abuse

Without a user-facing report mechanism, victims of harassment, hate speech, and spam have no in-platform recourse. They either suffer the abuse in silence or abandon the platform. Under the EU Digital Services Act (DSA Art. 17), any platform hosting user content must provide accessible flagging mechanisms — failure is a compliance violation carrying substantial fines. Beyond legal exposure, communities without reporting mechanisms develop entrenched bad-actor cultures because there is no friction on harassment. Platforms with DSA compliance obligations that skip this control face enforcement actions, not just poor community health.

Add a report button to every user-content component (posts, comments, messages) and persist reports to a dedicated database table. Backend route:

app.post('/api/reports', authenticate, async (req, res) => {
  const { contentId, contentType, reason } = req.body;
  const report = await db.reports.create({
    contentId,
    contentType, // 'post' | 'comment' | 'message'
    reporterId: req.user.id,
    reason, // 'harassment' | 'hate-speech' | 'spam' | 'other'
    status: 'pending',
    createdAt: new Date(),
  });
  res.status(201).json({ reportId: report.id });
});

The report button must appear on 100% of content-display components — a button on posts but not comments is a failing configuration. Wire the frontend component to POST to this endpoint with the content ID and a reason picker.

• ID: community-moderation-safety.report-enforcement.user-reporting

• Severity: critical

• What to look for: Look for a report/flag mechanism accessible to users. Check for a report form, button, or context menu on posts/comments. Verify that reports are stored and tracked (database table for reports). Ensure reports include reason, timestamp, and reporter info.

• Pass criteria: Every piece of user content (posts, comments, messages) has a visible report/flag button or menu. Enumerate all content-display components and confirm at least 100% include a report trigger. Reports are captured and stored with at least 3 fields: reason, timestamp, and reporter ID. On pass, report the count of components with report buttons vs. total content-display components.

• Fail criteria: No report mechanism exists, or reports are not stored. A report button that exists on posts but not on comments or messages does not count as pass.

• Skip (N/A) when: Never — reporting is essential for any UGC platform.

• Detail on fail: "No report button on comments. Users have no way to flag abusive content to moderators."

• Remediation: Add report buttons to all user content and store reports in a database table:

  // Backend API to handle reports
  app.post('/api/reports', authenticate, async (req, res) => {
    const { contentId, contentType, reason } = req.body;
  
    const report = await db.reports.create({
      contentId,
      contentType, // 'post', 'comment', 'message', etc.
      reporterId: req.user.id,
      reason, // 'harassment', 'hate-speech', 'spam', 'other'
      status: 'pending',
      createdAt: new Date()
    });
  
    res.status(201).json({ success: true, reportId: report.id });
  });
  

  Frontend component to render report button:

  import { useState } from 'react';
  
  function CommentCard({ comment }) {
    const [showReportModal, setShowReportModal] = useState(false);
  
    async function submitReport(reason) {
      await fetch('/api/reports', {
        method: 'POST',
        headers: { 'Content-Type': 'application/json' },
        body: JSON.stringify({
          contentId: comment.id,
          contentType: 'comment',
          reason
        })
      });
      setShowReportModal(false);
      alert('Thank you for reporting. Our team will review this content.');
    }
  
    return (
      <div className="comment">
        <p>{comment.content}</p>
        <button onClick={() => setShowReportModal(true)}>Report</button>
        {showReportModal && (
          <ReportModal onSubmit={submitReport} onClose={() => setShowReportModal(false)} />
        )}
      </div>
    );
  }
