Is there an online web service where people can report other people of bad landlords/places to stay? It might not be directly connected to fast traveling (in my case at least), but rather something like 2+ months. Although I imagine the same web service could be used in both cases..
So, if you're staying somewhere for example 2 months and if you had bad enough experience is there a place where you could warn other people by saying "look, don't go there, they were bad because of xy"?
