Worked great

A friend’s blog had “Let anyone register” enabled for quite some time and accumulated over 3,000 spam accounts. Installed this, went to its settings page and enabled it.

I appreciated it having a comma-separated whitelist and that the plugin listed the accounts it would delete with a 48 hour delay while providing a button to do it immediately.

Each button press removed 1k of the accounts quickly, and I pressed it a few more times and removed every non-active account on the site immediately.

Since we’re no longer allowing new registrations, I didn’t need the other features, so the plugin was disabled after doing its job securely, quickly, and easily.
