For the last few days there has been a large number of Chinese spam being posted to the forum. It's usually the same account posting the same message multiple times, once that gets banned another account is created by the spammer. Is there no rate limiting for new users?

Hi, I got abuse messgages concerning my FreeNas Box. It is sending out SPAM and is on a Spamhaus block list. I did not configure an SMTP-Server. I am using our Mailserver to send mails so I am a bit unsure how this came about. I searched the Internet and this forum but found nothing helpful...
