@Dragonrage That pattern appears to be homoglyph obfuscated. It's better to use the non-obfuscated number. Perhaps try: !!/blacklist-number + 1-833-317-0511. In order for a "number" to make an exact match, the pattern must begin with a digit or up to two of +,(,[, or { immediately followed by a digit. Append -force to the command word(s) if you really want to add the pattern you provided.
@VLAZ That pattern appears to be homoglyph obfuscated. It's better to use the non-obfuscated number. Perhaps try: !!/blacklist-number +1-707—341—8128. Append -force to the command word(s) if you really want to add the pattern you provided.
@VLAZ That pattern may be a North American number. If it is, please use a format which starts with an optional 1 followed by possible separator text and has the main number in the format 511-707-4375 where - could be a single alpha character or any [\W_]*+. Alternately, you can add the comment (?#IS NorAm) to the end of the pattern to force also using the alternate normalized form, or (?#NO NorAm) if it's not a North American phone number and it's incorrectly recognized as one. Perhaps try !!/blacklist-number 511-707-4375. Append -force to the command word(s) if you really want to add the pattern you provided.
