Registration and login are now required to post. This action was taken after 6 weeks of experimentation with spam blocking options. All options have some unintended negative consequences. At the end of the day an overwhelming majority (well beyond 2/3) of those voicing their opinion were in favor of requiring registration.
All banned IP addresses have been unbanned, so you can reach the board from anywhere.
Unfortunately, the spam problem is not over. It has gotten worse
After unblocking the banned IP addresses, we are now flooded with bogus registrations, so the spam goes on. If we don’t address the bogus registrations, our user list will become unmanageable. Currently the method of dealing with the registration spam is whacking, but it is much more labor intensive than IP banning since we get so much more spam and it will continue to grow.
Blocking email addresses is useless because of SMTP security loopholes. IP address are finite and real, but Email addresses are infinite.
We should be able to deal with the registration spam by periodically filtering the data base to delete all unconfirmed registrations, but I don’t currently have the application specific expertise to do so.
