Questions about example sentences with, and the definition and usage of "Investing"

A: @Kyanacy Ah, Facebook has a wall. But, there are quite a few social media sites that have 'walls'. In which case it would be close the Facebook Account. I'm not sure how to say Facebook Account in Japanese unless it's フェースブック・アッカウント
