It seems some wag dropped a bit of code into the site to place some (invisible) link spam at the head of the page back on New Year. I seem to have managed to clean it, so no harm done, and it seems to have been a Google-rank-lifting thing rather than anything actively malicious so it won’t have borked your computers at all, but if you see anything behaving strangely on the site do give me a shout.

Don’t make me break out a video of a dancing penis.
