This is a valid concern but if the community does not band together, this will never change. Continuing to use all platforms available to you is wise. Using subscription based platforms exclusively is not.
With the entire community using PS, property hunters will only need to go on PS to search for what they are looking for. By banding together as a community, you collectively drive all the traffic and response to one platform.
This then allows you to save on ALL the subscriptions fees you are paying because you would not need to do this anymore. Let’s eradicate the bullying together!
