From my experience as well, vent channels just aren't worth it, unless you're prepared to moderate it heavily and warn people/delete posts constantly etc server members WILL vent about extremely heavy topics. A set of rules asking members to keep it to simple day-to-day grievances pretty please isn't enough and also not really what people want out of a vent channel anyway. If your kitchen appliance breaks you can honestly just complain about it in the general chat and no one will care, a vent channel isn't necessary for that imo. Iirc FR staff also doesn't want you to have a dedicated vent channel in your discord servers if you're advertising it on the forums, even if you claim that the heavy stuff isn't allowed you're just better off not having one at all for the sake of yourself/the mod team, your members, and the site rules
