+  There are some occasions, where we need to add a simple "source" query parameter
+  to URLs so that we can see where visitors are coming from, as referrers only
+  work within browsers and with platforms that don't use special redirect mechanisms.
+
+  In order to maximize privacy in these cases, we remove the query parameter on page visit.
+  To keep transparency, we don't just delete the query parameter, but move them into the URL
+  hash "#disabled", to keep them visible, but disabled.
+
+  Here are some keywords, so that everyone who is curious will find this code snippet faster:
