Firstly apologies to anyone who had visited this site in the past few months and experienced pop-up advertising of various nature. I’d been very busy on projects and hadn’t had time to check the site and all this had gone under the radar. Google’s search indexing now hates me for it.
What had happened was my site has a plugin to check that people filling out the contact form are actually genuine people and not scripts or programs spamming me. I’d installed one of the commonly available (and recommended) plugins from the WordPress plugin library called Sweetcaptcha about a year ago.
Other users have had the same problem:
I guess this highlights the dangers of using open source or free software, and frankly I’m quite embarrassed that this has happened. I will remind myself that software that is free, usually has the cost recovered somewhere. There is no such thing as true altruism! Facebook sells your data to marketing companies, Google tracks your emails and search results and does the same, I went to sign up to Plev.tv the other day then found that my IP, movie metadata and all kinds of information gets sent back. In the case above these Sweetcaptcha guys rope you in with a nice free plugin and then down the track fill the thing with ads effectively wrecking your site.
