Seems like the Post Voting plugin would work really well with this.
I wonder, have there been AI-powered accounts so much so that they like posts, intersct and reach TL3? Because then that could be a problem.
Perhaps then the solution is to change promotion criteria to amount of points collected. But that will be a fundamental shift in the whole system. It would promote a more aggressive gamification (literally) of the forum to earn points. But you know, aggressively posting good, non-AI content could also be a good thing…
