Sorry, you have been blocked from accessing this website as your connections exhibit signs of abusive behaviour.

As a general rule, there are no restrictions on spiders and search engine bots accessing this website. However, we do expect bots to observe the usual niceties:

1. Obey the contents of robots.txt, including any crawl-delay parameter.
2. Send a user-agent string which unambigiously identifies your organisation.

Bots which fail on either of these fronts may be excluded from the site without notice.

VPNs and Proxies

You may get this error if you are using an anonymising VPN or proxy to access this site. If so, what it usually means is that other users of the VPN or proxy have been behaving abusively and we've had to block them. If so, there's nothing we can do about that, as we can't tell the difference between an abusive user of a VPN and a non-abusive user. The only solution is to use a different VPN or proxy, or just switch it off when accessing this website.
