Looks like this site is currently the victim of an automated spam attack. I may have to temporarily disable posting at short notice while I introduce a countermeasure. Apologies if that's the case.
You will understand if I don't reveal precisely what I've done to stem the flow... but as at MCiOS you may be asked a simple question from time to time. Don't take offence if this happens to you.
Having seen the posts before they were wiped I thought they might be taking the first baby steps towards xkcd #810. A good few years to go yet, though.
