Biggest opportunity: “comments”, “cookies” and “spam” aren't earning a slot. You list them, but you're not in the first 24 results for those searches. WordPress.org counts only your first five tags, so free the slot for a search you can win.

of downloads still active

At least 10K of 109.7K lifetime downloads are still running, above its category: the median Security plugin keeps 1.4%, across 1,061 plugins.

Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Security plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.

High removal-risk signals

63/100

Maintenance and integrity signals that tend to precede a WordPress.org removal. Not an official status, a heads-up to act.

  • Long abandoned. No update in 7+ years — the top precursor to removal once a vulnerability is found.
  • Compatibility drift. Tested only up to WordPress 5.2.30, well behind 6.8.

    (REVIEW UPDATED August 2021) Based on my long experience, I think this the simplest, fastest e most effective plugin to avoid spam in WordPress comments. I’m using this plugin on several sites, since years, and it works like a charm. Also on a big website with thousands of daily views (using .htaccess) P.s. It works very well with all versions of WP 5.x This topic was modified 5 years, 8 months ago by Jan Dembowski. This topic was modified 4 years, 11 months ago by Annonnimmo.

    If you don’t use any other spam filter plugins, then you can rely on this to stop spam comments for sure!

    There used to be 2 types of anti-spam plugins. The first one will block all comments, and also block shopping carts if you run a site where people need to pay. The second doesn’t work. There is now a 3rd category, and this one not only works, but also will not block shopping carts. This anti-spam works well with Clickbank and WP eMember possibly other carts as well. Thank you so much! The last update stopped the anti-spam from Tips and Tricks HQ with their WP Security plugin, and I was inundated with 100s of spam comments per day. Now, this solution works, and everything is sent to spam, without messing with my shopping cart. Thank you so much. mmoexploiters.com

    I originally found out about this plugin on Justin Tadlock’s blog. He was all for it so I figured it has to be a good one. I currently have it installed on all of my sites along with the recommended .htaccess rule, and now I do not ever see any spam! Awesome job guys! Thanks for a great plugin!

    Love the premise of this plugin, and the results are respectable & accurate. Can’t ask for more than that! If a project I’m working on supports comments, this is my go-to plugin to reduce spam.

    This plugin is 100% essential for any WordPress site. In fact, it would be great if this was added to core.

    Some of the plugins that I tried before promised cutting the SPAM but failed miserably to do so. I now believe that at my site [Link redacted], this plugin has served me very well.
