Seem to get a spam 'ghost' posting several times a week. Subject heading appears in the 'Recent Posts' list but not in any of the categories. There's one there at the moment entitled 'Does David Icke Blame Heel Lifts'.
I opened the first one a couple of weeks ago and there was a load of sales blurb, not bothered opening any since.
Actually the title of this last one 'Does David Icke Blame Heel Lifts' is quite plausible.
it seems they're now very good at reading the captcha images
