I had written to the administration and this is what they replied:

Hi,
We have been experiencing some issues with spammers/bots accessing our
pages, this has resulted in a huge overload in site traffic which has
impacted on our allocated bandwidth; we do anticipate spammers/bots and
usually keep things well managed and under control, however this latest
attack was unforeseeable and massive, although no spam was posted to the
forums the surge of site traffic was enough to soak up a huge amount of
bandwidth allocation which in turn triggered the server to close down. We
had no warning of this, and as a result couldn't post an announcement to
advise members of the impending downtime.
The situation is being dealt with and the site should be up and running
again shortly, hopefully within 12 hours.
Apologies for any disruption caused.
Best regards
BCF Admin.
