@redpilled you can provide a paid only forum, access to which is on the basis of a vetting process involving an automatic test and existing members of that paid forum.

Also, if trp.red provides tools for the people running the Tribes to make their own money, they will gratefully pay a cut of that.

Another thing to consider would be, rather than a subscription model, a "lifetime" payment of something that would discourage Sybil attacks and spam, perhaps $1. This would prioritize your responses slightly above those who did not pay the $1. If you have fewer than 10 accounts, $1 for each may be worth it. But it would discourage spam because to try to automatically generate 1000 accounts, most of which will be flagged, becomes expensive. The money from the spammer subscriptions could even be paid to the mods and men reporting spam.

You can even make bounties, or "pre-tip" someone to comment on your post. This has been done in the world of open-source development, e.g. gitcoin. I have a problem, and need advice on it. I pre-pay an amount. If someone solves that problem, I pay. It could even be earmarked for a specific user, say, if I wanted a reply from Whisper. If I didn't like what he had to say, well, too bad, I can earmark for a different user next time. In the unlikely event that Whisper just replied with a '.' or other bad faith behavior, that could be a matter where the mods get compensated for their review work.

In general, if TRP finds anything that users can pay to other users, a business, or vice versa, or anyone else, and help get that flowing, money will come back to TRP.

One thing to keep in mind with any of this, though, is that $1 for a middle class, twenty-something nerd in the USA is very different than $1 for a teenager or for a lower-class guy in India.

Other ways to contribute to TRP, to earn instead of buy, may be worth offering to deal with the need for market segmentation.
