I periodically get automated emails from people I mostly don't know or know only remotely asking me to update some contact information for them... and it's always from Plaxo. Looking at the headers, the origin looks legit.
This seems to be a service that maintains contact information for its users. However, I don't wish to participate. Does anyone know much about this service, including any issues they might have had with privacy, or if there are any known spoofs or exploits that masquerade as Plaxo? Thanks, -Philip
