Biggest opportunity: Swap “anti spam” and “registration” for “symbols” and “emails”. “anti spam” isn't earning its slot: you're not in the first 24 results for its own search. “symbols” sits at #10 untagged, close enough for a declared tag to move it up. “registration” isn't earning its slot: you're not in the first 24 results for its own search. “emails” sits at #15 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

How it's measured →2.1%
of downloads still active
At least 1K of 48.3K lifetime downloads are still running, above its category: the median Login & Users plugin keeps 0.7%, across 1,477 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Login & Users plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
This plugin shipped 6 releases in the last 12 months, and every existing install that updated counted as another download. wp.org publishes no split between first installs and updates, so we show the raw rate rather than guess at one.

What to do about it
- Swap “anti spam” and “registration” for “symbols” and “emails”. “anti spam” isn't earning its slot: you're not in the first 24 results for its own search. “symbols” sits at #10 untagged, close enough for a declared tag to move it up. “registration” isn't earning its slot: you're not in the first 24 results for its own search. “emails” sits at #15 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.
- Slipping on “author slug”. Down 5 places since 2026-09-18, now #14. Check what shipped around then, and what moved above you.

Brilliant plugin that solves all sorts of issues with user names

I am wary of hackers, so I have been trying to keep out spam accounts. I even have a captcha to sign up to comment, but the bots still get through, like 200 a day. I have been daily bulk deleting all those, “telegram,” “blogspot,” and “.ru” accounts. This plug-in relived me of the burden of having to do that so much. I think this might be one of my ‘essential’ plug-ins for any website build for new website clients from now on.

I was looking for a “Not allow these names” and this plugin did that for me. Now I can block mail.ru, blogspot, www., etc when trying to register. The admin area could use some love… I think if the addon better replicated the default wordpress admin style things would be better. remove hamburger in top right corner fix spelling “Extentions” to “Extensions” fix padding / margin spacing between UI elements sidebar admin menu name is huge “Restrict Usernames Emails Characters …” should be “Restrict Usernames” or something really short I liked and appreciated how the “leave review” banner was at the bottom of the page and not in my face at the top. That’s why I left this review… Great job! Thanks!

wordpress的注册地方有两个，一个是官方提供的默认注册位置，你的插件只能对默认注册用户过滤，但是现在大多数都用的Elementor 提交的注册表单，我希望你能添加对Elementor提交病保存的 用户过滤的支持， There are two registration places for wordpress. One is the official default registration location. Your plug-in can only filter the default registered users. But now most of the registration forms submitted by Elementor are used. I hope you can add support for filtering the users submitted by Elementor, This topic was modified 3 years, 4 months ago by lijonghui.

block email domains doesn’t work at all and there is no support to reply. Simply useless plugin.
