Someone else posted about not being responded after replies - see the threads below. Do you think its time, hosts started leaving negative feedback for things like when a person contacts you, says they are coming and then doesn't show up? I think it might help change the behaviour of warm showers guests if they started getting negative feedback for these fairly small minor misdemeanors.
Yes they are minor but some people have to wait around and you feel you have to make plans around this commitment so its very annoying if someone doesn't show up even if haven't gone to any extra effort to prepare for them.
Its also annoying when people don't leave feedback promptly - i felt it as a lack of gratitude. And had asked for feedback so was expecting it to be soon. The person did eventually leave feedback but i think its easy enough to leave it if people have smartphones and laptops. They could even do it from your own place before they leave if they are concerned about not having internet connection.
Also when people don't get back to you when it would be polite to do so. Of course if hosts don't reply to initial enquiries from guests that, in my view, would not warrent negative feedback since there is already a system keeping tabs on this.
Given how big the community is now and it seems that quite a lot of people may take their hosts a little bit for granted, there needs to be some way of motivating people to do the right thing. When the carrot doesn't work, there has to be a bit of stick.
