The last couple of days I have received emails informing me that "Anonymous" has left a comment on a post from months ago. The comment bears no relation to the post concerned - one asked if I needed anyone to write posts on the blog, today's if I was experiencing browser issues. Both posts asked me to email them and supplied dodgy looking links. The funny thing is those "comments" don't actually show up on the post concerned
I would suggest that no-one clicks on those links if you get such an email. I'm not going to restrict comments from those who wish to remain anonymous as I regard, unlike others, comments to be an integral part of the blog. Just be careful out there guys!
