Facebook has begun a trial which allows users to pay $1 to send messages direct to people who are not their friends.
The fee will mean messages go straight to a recipient’s inbox rather than the Other folder which contains all unsolicited correspondence.
The trial is only for a “small number of people” and is initially being tested just in the US.
Users will be able to receive a maximum of one paid-for message per week, and no more than three each month.
“Several commentators and researchers have noted that imposing a financial cost on the sender may be the most effective way to discourage unwanted messages and facilitate delivery of messages that are relevant and useful,” the site said in a statement.
