While the bots seem to be primarily targeting NSFW games, they are also posting these on other games.
We've been getting these on our family-friendly game. This is a huge issue for us. Our only recourse at this point seems to be to disable our comment section entirely.
Ideally we would like an option to hold all comments for manual review before being publicly displayed on our page. I would much rather legitimate comments be held in review for a few hours, than for explicit sexual content to stay on our page for a few hours.
