I'm trying to send a cute guy a message and its saying he only accepts messages from certain users. What's this mean
When setting up a profile, POF lets users discriminate the messages they recieve by age of the sender or who the sender previously messaged. It's possible you fall into one of these categories. It should also list this on the bottom of his profile.
He's not into you, and he probably won't even reply to your message. Even if he does, it won't go anywhere and he'll randomly stop replying to you.
