1) What version of B2evo do you have. If it is in the 1.9+ range you should be fine, if it is older, please upgrade. There is a lot of improvement in antispam measures in recent versions.
2) Is the Turing Test plugin activated? Check the plugin setting in the backoffice. The dot before the plugin's name should be black.
3) If the TuringTest plugin doesn't wok properly, you might consider the Captcha plugin.
4) The links does work, remove the trailing comma. It is an interesting exploit. The site sportsguns.co.uk has been hacked. But this is of no interest to you.
In B2evo you have enough possibilities to counter spam. Unfiortunately there will always be new methods that require new solutions.
