Implementation of http:BL for Drupal. It provides IP-based blacklisting through http:BL and allows linking to a honeypot.

Code

function httpbl_comment_presave($comment) {
  if (variable_get('httpbl_check', HTTPBL_CHECK_NONE) != HTTPBL_CHECK_COMMENTS) {
    return;
  }
  if ($logs = variable_get('httpbl_log', HTTPBL_LOG_MIN) == HTTPBL_LOG_VERBOSE) {
    watchdog('httpbl', 'Checking user\'s IP during comment pre-save.', array(), WATCHDOG_DEBUG, NULL);
  }
  if (httpbl_check()) {

    // Comment user's IP found in Project Honeypot.
    // Let them know
    drupal_set_message(t('Your comment was rejected because your IP address is ranked "suspicious" by Project Honeypot.'), 'error', FALSE);

    // alter the comment subject and body
    $comment->status = 0;

    // Force comment to unpublished status
    $comment->subject = t('(THIS COMMENT HAS BEEN HONEY-BLOCKED!)');
    $comment->comment_body[LANGUAGE_NONE][0]['value'] .= t('<strong><<<<<< This comment was blocked and unpublished because <a href="http://www.projecthoneypot.org/">Project Honeypot</a> indicates it came from a suspicious IP address.</strong>');

    // Add to our statistics
    if (variable_get('httpbl_stats', TRUE)) {
      variable_set('httpbl_stat_comment', variable_get('httpbl_stat_comment', 0) + 1);
    }
  }
  return;
