iFreeChat review
iFreeChat offers free adult chat rooms and describes guest access by nickname. Its public directory separates rooms run by the site from rooms made by visitors.
Check who runs the room
Official rooms stay in the directory and have both human and automated moderation. Rooms started by visitors are temporary, and the site says those rely on automated checks and reports from the community. OnlineFreeChat spells out when visitors can share private chat logs with moderators.

Permission to share and information collected
The terms require a signed release or written consent for identifiable people in material a user posts. The privacy policy says the site can collect IP addresses and usage details. The terms say the company can act on reports while leaving users responsible for what they submit.
Anabel’s take
I’d pick a permanent room the first time. A narrow topic might draw me into a temporary room, but I’d pay more attention to how it handles reports.
