Lately my blog has seen a number of new users registering. The strange thing is, is that this user uses an email adress that looks the same time after time. He/She then doesn’t post any information / comment. And the next day another user is added.

You can see the following image copy-pasted from my admin panel.

I’ve tried emailing the above email adresses, but all bounce. This means that the person adding the users is using a fake email adress. This means that i feel no sorrow when i delete these users again.

But the thing is, i’m interested in finding a plugin or something that can let you block account names automatically. Now it takes a manual handling to remove these users. Do you know anything that can do this?
