+# A simple finding for obtaining a single User.
+#
+# While using `User.find_by` directly is straightforward, it can lead to a lot
+# of code duplication. Sometimes we just want to find a user by an ID, other
+# times we may want to exclude blocked user. By using this finder (and extending
+# it whenever necessary) we can keep this logic in one place.
