I'm looking at KAM.cf. There is this rule:

I'm wondering if there is a good reason why a singe period is used
instead of something like \s+ which would catch multiple spaces
whereas a singe period doesn't.
Because '/indian.based.website'/ will match 'indian-based_website' but
\s will not.
This is the real reason (or at least, it was for all of my contributions
to KAM.cf). I was also concerned about tricks like , which is
visibly a space but has all the technical characteristics of
non-whitespace. Using "." was easier than knowing everything about
unicode codepoints.
