I've had a couple of comments recently that have been in Chinese and Anonymous ones advertising some website or other so for a short time I'm only allowing comments from people with Google accounts and have also enabled 'word verification' I aplogise to anyone who'd like to comment but doesn't have a Google account but I'm hoping this will deter unwanted commentors.? If anyone can advise what other option there is - eg Registered users (not sure what that means) which would make it possible for genuine comments for those without a Google account, please let me know.
EDTED - My concern is that if it's Spam it may cause problems. But Jane has said it is Spam and can bypass 'word verification'. So I'll wait and see.
