I just deleted over 700 “users” who registered to my blog. Most, I am sure, were just spam bots, I am sorry if some of you were real people.
Registering is now blocked as is commenting. I got tired of all the notification e-mails from WordPress. In over a year there was only ever two comments that were not spam. It’s just not worth the effort. If you want to communicate with me more directly, use my Google+ profile
