I am noticing that every day or so user accounts are being created on my wordpress blog. I have no idea who these users are and to date they have not posted, but I am worried that they are being created to be used for spam or some other undesirable purpose, any idea what they are and whats going on anyone? Also Is there a way to stop users creating accounts?
These are the accounts created so far
