Thanks for reporting it. I installed a spam blocking utility recently that allows me to auto-block registrations from specific countries that massively spam us, and also allows me to deny registration from any connection that hides its header information (a key feature of anonymous proxies that are used by people wishing to troll / spam / hide their IP address / location / etc.)
It is likely your friend was using such proxy connection - either unknowingly via their ISP or perhaps via a software tool or browser privacy setting - but this isn't the intended use of the utility so I've disabled the header proxy settings which will hopefully tone down the aggression of the tool.
I've also disabled the default "Not accepting registrations" message and replaced it with one that encourages people to get in touch - along with a link to our contact page:
Our anti-spam measures have detected a problem with your connection and blocked you from registering at this time. If you believe this is an error please get in touch
I'll post an announcement in the site news forum to let anyone know who's received a knock-back recently to try again - we're certainly still open for business and wanting lots of new members.
Cheers,
Shaun
Note: I've made this change across all of the forum sites!
