The Bioscope would like to apologise to any visitors to this blog who are finding Adsense ads appearing on posts if they come via a Google link. This is a feature that WordPress has introduced, and I can do nothing about it. I understand that if you are a regular visitor, or if you are logged into WordPress yourself, then you do not see the ads, but if you a newcomer or an infrequent visitor, then the ads will occasionally crop up. There seems to be nothing I can do to change this – you can’t even pay to make them go away. So I just want to make it clear that I have not sanctioned the use of this blog to sell anything to anyone, and I am very unhappy that it has been hijacked in this way, contrary to what was my understanding when I first signed up with WordPress. If I can change things, I will.
