Genuine question about how to report abusive users in a live chat from someone who's tried the obvious routes. How fast moderation responds tells you more than raw member count, speaking only for my own city, which is the whole problem with report chat rooms. If abusive chat rooms is your priority, nothing improves until you run a reverse image search on suspiciously polished photos.
The abusive report case is instructive — it is worth checking how many first messages actually land before you look at raw member count. Report chat rooms is the clearest case of it — the platform hides read receipts on the free tier, so people churn out before anything happens.
Report chat rooms is where I'd start, since the platform buries the cancellation flow, so it pays to keep the conversation on-platform until you have met. The reason how to report abusive users in a live chat keeps coming up is simple: the reply rate is the number worth watching, not how slick the interface looks. Anyone who has tested report chat rooms properly, please weigh in.
