When someone clicks on the link “Help us find the real [person’s name here]”, the first link that pops up is a link that says “I am the real [person’s name here]!” Users who are less than bright tend to interpret the latter to mean that the actual person can be contacted through that link. They don’t realize that they are voting for their own page as an alternative to the page they’re looking at. (See Kevin Smith’s page as an example, where some poor sap named Bryon Frank has unwittingly identified his own page as an alternative to Kevin Smith’s.)
It should be possible to vote against a link like this as well as for it. This could be used to identify such mistakes more easily.
