I have been troubled about this blog since John told me it was generating spam in his feeder. I went over all the settings and have been more cognizant over who is registered as a user. I deleted a couple of suspicious looking users and then i have been besieged by new users with similar looking suspect email addresses. I am tired of being notified them opening up the site and deleting them throughout the day so i have tried to change my settings to bar new users from registering. sorry for anyone who would like to register to comment. i will try to open it up for that again down the road. for those who are registered are any of you still there? please let me know about any spam related incidents with this site.
