I’ve been ignoring this problem for a while but decided to deal with it after getting another blog of bogus user registrations over the weekend. Apparently there are some SpamBots that go around and register users on WordPress hosted blogs in hopes that users will have posting permission by default. These bogus users used to appear on the NCLUG blog from time to time but lately there have been a lot of them 10-15 per day. I try to delete them but there are too many.
I have installed a CAPTCHA plugin which adds a requirement during the user registration process to enter the code displayed in hard to read letters and shapes. I apologize for the hassle but there wasn’t much of a choice.
