I see Serge has implemented a Spam Blocking mechanism for all the vbCity Blogs. See Comment spam battle - Captcha control implemented on blogs.vbcity.com. Hopefully this will help combat the ignorant SPAM postings without inconveniencing posters too much.
I have tested it out by replying to Serge's post and my comment has gone in successfully.
As I said to Serge the downside is when I need some extra viagra or feel the need for a bit of on-line poker I shall have to rely on Google rather than a quick look at SPAM comments in my own blog. But that is a small price to pay :-D
