+.Sh NOTES
+Sometimes the reported number of failed attempts can exceed the number
+of attempts that
+.Xr blacklistd 8
+is configured to block.
+This can happen either because the rule has been removed manually, or
+because there were more attempts in flight while the rule block was being
+added.
+This condition is normal; in that case
+.Xr blacklistd 8
+will first attempt to remove the existing rule, and then it will re-add
+it to make sure that there is only one rule active.
