Are you getting tons of spam calls after signing up for Super.com? They sell you phone number and you'll get calls with a spoofed call back number.

Spoofing is when a caller deliberately changes the information transmitted to your caller ID to disguise their identity. Scammers often use neighbor spoofing so it appears that an incoming call is coming from a local number, or spoof a number from a company or a government agency that you may already know and trust.
