Or just upvote and comment in positive ways. You don't even have to like it, read it, or care. If you see someone posting anything that appears like a real person in some niche, upvote it every time! That one vote or comment matters to that person and might be the difference between them posting again or not. Encountering no response kills people's efforts and growth. Never be negative. You're only hurting all of us. Assume you do not understand, give the benefit of the doubt, be kind, be empathic. And if you're admin, kick the most negative 0.01% of users that make 90% of the negativity!
