+            Hi,
+
+            Thank you for raising an issue to help improve Nautilus. We're sorry this particular issue has 
gone unnoticed for quite some time. To establish order in issue tracker we try to ensure that every issue is 
correctly labelled and triaged to get the proper attention.
+
+            This issue will be closed, as it meets the following criteria:
+            * No activity in the past 18 months (3 releases).
+            * Unscheduled. Not associated with a milestone or with ~"2. Deliverable" or ~"2. Stretch" 
project planning labels.
+
+            We'd like to ask you to help us out and determine whether this issue should be reopened.
+
+            If this issue is reporting a bug, please can you attempt to reproduce on the [nightly Flatpak 
Nautilus](https://wiki.gnome.org/Apps/Nightly), to help us understand whether the bug still needs our 
attention.
+
+            If this issue is proposing a new feature, please can you verify whether the feature proposal is 
still relevant.
+
+            Thanks for your help
