This is what I’m saying. Posting/voting isn’t a limited resource that can be distributed unfairly. People do it or don’t do it as much or as little as they want. Why restrict that on an ecosystem that you want to grow?

If the issue is compute, or resources to run the compute, or admins to maintain the compute environments, then focusing on those issues would be better. Ask for donations to add a new server, encourage people who can to set up their own servers to distribute the load, request that more people play an active role as admins. But restricting engagement/activity of your users sounds like the beginning of the end of your ecosystem…
