Works Great
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.

It's nice but need some "polish"
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!
