Hey, by doing a reverse lookup online anyone can reveal the entity behind that anonymous ID. That ID could be anything: a phone number – thus, a reverse phone lookup; or an email address – a reverse email search it will be; or an SSN number. It is more tricky to do a reverse lookup for an image but other reverse searches include a reverse DNS lookup which basically identifies a host name by the site’s DNS entry. But one of the most popular reverse lookups is, of course, reverse phone lookup. You can do it for free, though the info supplied will be somewhat limited. Paid cell phone searches are more detailed and often include the name of the owner, age, address and other spicy details.
That’s said, go ahead and try out the reverse lookup for yourself!
