Have you tried adding certain words to Admin → Customize → Watched Words → Require Approval?
From your screenshot, I’d try adding these words:
- cash
- credit
- money
- loan
- toll-free
- customer care
- care number
- 0779*
- helpline

It can be slightly inconvenient for users, but I have Discourse send a webhook to a Firebase cloud function (free) that pings my phone in a Slack chat room, so I can often approve posts in moderation within 60 seconds from my phone, if I’m awake.
