This is about a theme distribution site called Templatesbrowser dot com. I intentionally do not link to them. They are showcasing various authors’ themes and providing direct downloads for them. To make things much worse, they have added code to the footer of these themes that call the original site back and add hidden links to the themes once they are installed. It could also be used to run other malicious code. I strongly suggest that users stay away from downloading and using anything from them. This is pretty darn shady. Thanks to Milo, Derek and others for staying on top of this.
