The tech blog Mashable reported early Friday that some users trying to message Zuckerberg are offered the option to pay $100 to ensure that their missive reaches the Facebook CEO's inbox. Without paying, the message would likely end up in Zuckerberg's "other" message folder, an oft-overlooked purgatory between the spam folder and the inbox.
Facebook says it's testing the "extreme" prices to "see what works to filter spam. The company is also testing a service that lets people pay $1 per message to route communications to non-friends' inboxes.
Zuckerberg has more than 16 million followers on the site.
