As posted yesterday, we temporarily disabled new user registrations for all domains. Today we have changed the block to only those using Gmail.com, Hotmail.com or Outlook.com addresses - new users trying to register an account from any of those domains will see a warning that registrations from their email address have been disabled. Unfortunately this may still allow some spam bots to register and post unwanted content, but as the majority of the bots had been registering from those three domains, we will continue to block them until it is determined that there are fewer attacks from those addresses.
Users with addresses from other domains and users already registered will not be affected and the forums will continue to operate normally during this time.
Once again, we appreciate the patience of those who are unable to register and hope to have everything back to normal soon.
On behalf of the Pioneer team, thank you!
