Facebook is reportedly charging its users $100 to send a message to the founder of the social networking site, Mark Zuckerberg.

Chris Taylor, a senior tech analyst at Mashable reported on Friday that his attempt to send a message to Mark Zuckerberg made him realize that Facebook's experiment of sending message to VIPs or those not on friends list is chargeable.

According to the report, Facebook said that messages to Zuckerberg's "real" Inbox will be charged $100. Messages which are not charged for sending will be dumped in Zuckerberg's "other" message folder. The report also quoted a Facebook spokesperson saying as "We are testing some extreme price points to see what works to filter spam."

The latest report of Facebook charging $100 for messages to the CEO is viewed as an expansion of the site's earlier experiment of charging $1 for messages which are sent to people who are not in one's friend's circle.

"Today we're starting a small experiment to test the usefulness of economic signals to determine relevance. This test will give a small number of people the option to pay to have a message routed to the Inbox rather than the other folder of a recipient that they are not connected with," the Facebook blog post explained.

"If you want to send a message to someone you heard speak at an event but are not friends with, or if you want to message someone about a job opportunity, you can use this feature to reach their Inbox," the company added.

"For the receiver, this test allows them to hear from people who have an important message to send them."
