Hi, and thanks for your contributions. Another user Ezra Jenks has pointed out that some or all of these trails are still frequently (possibly illegally?) used by the public. However your private access tags remain in place. https://www.openstreetmap.org/changeset/168677183
I assume you represent the property owner - If you still allow public use despite this being private property, we also have the "permissive" access value to show that.
Also, thanks for not simply deleting these trails. Perhaps you are already aware, but there are myriad benefits to marking with appropriate access tags instead of deleting. https://wiki.openstreetmap.org/wiki/Why_we_won%27t_delete_roads_on_private_property

Let me know here if you have any questions or further input.
