Comments sections have something of a reputation for housing negative remarks and being a source of issues for content creators. This sometimes dissuades creators from using this resource, and hearing what their community has to say. So what can you do to help keep your comments section constructive?
One important way to ensure your community feels heard is to reply frequently to your comments section, and respond to the things being posted. If there is an issue with your project, this can feel like a daunting task. However, active developers and content creators are typically rewarded with a strong and growing community, who appreciate the effort going into interacting with them.
Encouraging discussion on your comments is another way to increase activity and gain valuable feedback. Commenting yourself, with questions for your community or soliciting feedback can bring more users into the discussion, and replying regularly will help keep that feedback coming in.
If your comments section does receive spam, or other posts which are violations of the community guidelines, it's important to moderate those comments so that your community can find and read the comments that have content to them. Itch.io does not moderate comments sections, so staying on top of the activity on your page is a must!
