+# Bool. Enables a proof-of-work based deterrence against scrapers
+# on profile and status web pages. This will generate a unique but
+# deterministic challenge for each HTTP client to complete before
+# accessing the above mentioned endpoints, on success being given
+# a cookie that permits challenge-less access within a 1hr window.
+#
+# The outcome of this is that it should make scraping of these
+# endpoints economically unfeasible, while having a negligible
+# performance impact on your own instance.
+#
+# The downside is that it requires javascript to be enabled.
