WordPress plugin Random Posts Widget Configurable is misbehaving

I was looking for some WP plugin that generates widget with a list of random posts in the sidebar. First hit was Random Posts Widget Configurable – so I downloaded and installed it. Works fine – but there was some border I didn’t like to decided so remove it. While lurking into the code I spotted this one:

Seriously? Some shop AD? There is already some posts about it on WP site: http://wordpress.org/support/view/plugin-reviews/random-posts-widget-configurable

So – remember to check the code of plugins You use. I’ll try to write a post about WordPress security – It could be helpful for some of You.
