In case you didn’t know, Facebook also has an “Other” inbox which is intended for the messages that Facebook thinks you don’t like to read, i.e. messages from strangers or from other pages. “This test is designed to address situations where neither social nor algorithmic signals are sufficient. For example, 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,” Facebook announced last month.
Explaining the reason for the $100 charge, a Facebook spokesperson said, “We are testing some extreme price points to see what works to filter spam.”
