How do you handle/moderate commercial members?

Wonderful community btw. My community is involved in finance, so the propensity for snake oil salesmen and con men is high, hence my question about paid commercial accounts. Con men and spammers are less likely to game a system if more than time and typing are required to get involved. We’ve thought about baking in minimum registration length or minimum post count, but that would undoubtedly create additional barriers for commercial accounts to register, and I could absolutely see registrations dry up.

Thinking about this a bit. You could consider using the Trust Level system in Discourse. Similar to how TL0 isn’t allowed to send PMs, you could restrict posting Marketplace to TL1 and higher.
It’s a small speed bump for real participants, but it cuts spam massively.
