"Is that so?" Sai asked when Usopp mentioned everyone being from his crew. "That's interesting, and good to know." He leaned forward with his hands folded in front of him, trying to appear thoughtful. "When I was looking into everyone from my world, there seemed to be a common connection among them in that everyone knew Uzumaki Naruto, one of my teammates, and some were connected by no other means. It's possible that the connection for your world lies with someone in your crew?" It was still possible that there was no connection at all, and this was all just coincidence, but that was something to go on.

Usopp could do whatever he wanted with the bulletin post as long s the message got across, so the ninja just nodded to the last statement. He wouldn't be sure if Kakashi would have any interest, but there was a chance.
