It’s not a topic issue. The discussions are largely around platforms and custodians. They bring lots of ethical problems. Anything on this page is relevant to personal finance:

If someone managing their personal finances wants to ask how to avoid the bad players and still achieve their goals, it’s relevant. But Bogleheads is not keen. I don’t recall the particulars (it was over a decade ago) but it wasn’t topic related. It was just a conservative moderator or crowd who don’t want ethics getting in their way or cluttering their view.

Tor. I wonder if that is a more fraud or trolling concern. Or maybe for financial houses more of a US law concern.

Certainly not a legal issue in the US. Tor works ATM on Bogleheads. Cloudflare is often chosen out of ignorance by admins who don’t even know what Tor is, or at least don’t know that most Tor traffic is legit. It’s usually a lazy move. I don’t recall the details about Boglehead’s tor hostility but they’re reachable over Tor right now.
