I had someone e-mail me today that was disappointed to find user images were not being displayed on Flickr. I did some testing and the culprit was farm4.static.flickr.com. It seems Flickr are now using these hostnames for user images aswell as adverts.
Because of this, and because I don't want to block legit graphics, I've removed the following from the hpHosts database;
These removals will be reflected in the actual hpHosts HOSTS file on the next update (due for release by Wednesday next week).
As an aside, removals from the database can now be monitored if you wish as they are now recorded in the following file;
If you come across any other hostnames in hpHosts that cause problems such as this, please do let me know.
