Regex Editor & Tester

Matches the Spanish word 'publicidad' (advertising) in any case combination, even when letters are separated by arbitrary characters. Each character class permits common obfuscation substitutions, such as 1, |, l for 'i', @ or Ü for 'u', and 4, ä, @ for 'a', so leetspeak variants like 'publ1c1d@d' are caught. Typically used in spam filters and content moderation to detect keyword-evading advertising text.
