I don't use my real data in any service with a bad privacy policy. I removed most of my data from facebook (wich policy I didn't accept until they changed it because lot of complaints). And I don't use untrusted facebook aplications (wich are the most of them XD). Well, I use paypal, who now give your data to a lot of financial companies :S

Whatsapp's privacy policy is the worst I saw. It can even change without notice the users (that's illegal in my country, Spain) , and it is considered accepted if the user continue using it after the change. They say that the user is responsible of re-reading from time to time their privacy policy and search for changes from the older one. wtf?

In PeterBornx Java Port I used a false IMEI and a alias phone number from fonyou.com to my real number. In Yappari I have to use my real IMEI but I continue using not my real number.

I tried to register a completely false phone number but the free SMS services I tried didn't work.
