While it is weird, it's worth noting that the transaction information it shows just shows who paid who and an optional narrative. They don't show actual dollar amounts. That being said, you can always post privately. Not sure why people post publicly.
Was going to reply but you've basically said it. You could pay an ex-partner when you're not supposed to be seing them, a liquor store when you're supposed to be sober, or a sex worker when you're supposed to be ashamed. Not showing dollar amounts doesn't make this sane.
