Just this afternoon, my sister site http://nursingcrib.com has experienced some kind of a re-direction that was cause by a script of Advertlets. Websites that are running the advertlets widget are being prompted that the domain has expired. If you are running the advertlet widget, please take it out now. I don’t know what happened to http://advertlets.com, it seems that their website has been hacked. Here’s how it looks like.

To remove the script, just login to your wordpress admin and take the script out on your sidebar.php. That should clear the problem out. I hope that advertlets will issue some explanations on this matter.
