Estimated value

What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.

Est. annual revenue

N/A

Est. acquisition value

N/A

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from.

    I was using another plugin that blocked email addresses and domains and was still getting dozens of bot registrations per week. It was like playing Whack-A-Mole. I replaced that plugin with No-Bot Registration and they dropped to zero.

    It’s the only plugin that correctly filters USERNAMES. Other plugins claim to filter, but they only work for emails, not usernames or both like this one. Congrats! P.S.: You could consolidate all the information from your other plugins, but that’s honestly the only (sorry) negative thing I can say about your creation 🙂
