Are you familiar with the paraphrase when you ask a question you will most likely receive an answer? Well, funny because yesterday I asked the question whether social networking sites have the ability to protect themselves from competitor means of access? And today I find a reference relating to the same issue on TechCrunch. Evidently, Facebook block ads with the names of competing social networks, like "MySpace" and "Friendster", which is a direct way to censor out opponents.
Although, the Facebook ad filtering system may need a bit more work, as names like "Bebo" and "OpenSocial" do get approved to publish commercial ads, it is definitely one way to send the "store manager" out to supervise.
