I'm having a brain freeze right now. Does /w+ match : ONLY aaaa, bbbbb, ccccc, ect.... or will it also match abcds, dfgdfg, dsfgrgr, ect.....
The latter. (And I assume you mean \w+, not /w+ .) The \w character is a special character that matches any of [a-zA-Z_0-9]. After the first \w matches (say "a"), the next one (as per the + operator) has no memory of what the first one matched.
If you actually want to match strings that are "the same character repeated over and over again", I think you'd need to use parentheses to remember the first match. Something like: /(\w)\1{3,15}/
If I'm parsing things right, the \w should match any (single) alphanumeric; the parentheses should cause it to be remembered, and the \1 should result meaning "match the same character that the \w matched".
Note that you probably would NOT want to use: /(\w)\1+/ , because then any double-letter will be caught by this regex.
