Are these scam sites?
omarchowdhury: You are completely wrong to think that websites that list phone numbers and other people's histories with said phone numbers are perpetrating the actual calls. Site such as WTFcalls.com are only trying to seek traffic through ranking for phone number keywords in Google (because it is very easy to do so - those phone numbers occur on very few other pages on the web).If you look at this example page:http://wtfcalls.com/649-200You can see that WTFCalls has automatically generated every conceivable phone number in the United States - in an attempt to rank highly for those numbers in search engines. WTFcalls.com receives around 200,000+ unique visitors monthly, almost all from search engines. Their ad revenue from Adsense should be a sustaining amount.Not bad for simply creating a script that makes a page template optimized (to rank in search engines) for every known phone number (example: http://wtfcalls.com/n/649-254-1011).I put a random number into Google:http://www.google.com/search?hl=en&client=firefox-a&...Look who came up first! WTFcalls.comRest assured.
