+# Keep in mind that in regexp rules, dots may or may not be escaped.
+# So if you want to exclude a rule like:
+# `/example.(com|org)\/ads/`
+# You should replace the dot `.` with `(\.|\\\.)`, resulting in:
+# `\/example(\.|\\\.)\(com\|org\)\\\/ads\/`
+# This regexp will match and block both:
+# `/example.(com|org)\/ads/`
+# `/example\.(com|org)\/ads/`
+# See an example: https://regex101.com/r/L7CsOZ/1
