Since there is an ongoing problem with hosts not responding to messages, I would kindly suggest that an additional filter be added during the next update.
What I envision is a filter where the guest, when searching using the Advanced Filters at the page bottom, can select if a minimum response rate is require in the search returns. Perhaps something like 50%, 75%, or 100%. This way, the guest knows there is an increased probability of getting a response. Even a "sorry, can't host" response is better than no response.
Yes, the filter may cause the responding hosts to get more guests. A response does not mean a Yes, to the request so the actively responding hosts can always decline for whatever reason.
Just a thought. Tailwinds, John
