@Cow That pattern looks like it's already caught by Potentially bad keyword in body and Potentially bad keyword in answer Append -force to the command word(s) if you really want to add the pattern you provided.
@JeffSchaller 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 969-279-8078 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 969-279-8078. Append -force to the command word(s) if you really want to add the pattern you provided.
@Cow A normalized version, {{'919692798078'}}, of that pattern is already on the number blacklist. You can use !!/bisect-number 91)((+9692798078 to determine which entries on the number lists match that pattern, which would tell you: Matched by the following: 9692798078(?#no noram) on line 3340 of blacklisted_numbers.txt: 9692798078 found normalized 919692798078 on line 3341 of blacklisted_numbers.txt: 919692798078 found normalized
@SmokeDetector moderator declined my flag, but I am 100% sure this is spam. See MS search. Also I think the old posts are also wrongly given false positive.
