Keeping your privacy these days can be quite a challenge…
Two of the more useful tools in helping keep your identity hidden are disposable email addresses and phone numbers. Another tool which can be used for good or evil — is Caller ID Spoofing (yes, it’s legal). We actually use this for our corporate PBX because our VOIP provider shows the wrong phone number for our outgoing calls and I used a spoof script to make sure it shows the correct callback number.
